On Tuesday, March 1, 1988, Teri Lass of Norwalk, Iowa, claimed she found her 10-day-old infant daughter, Tamara Lynn Lass, unresponsive.

The child was later pronounced dead.

With no visible injuries, authorities first believed the infant died of Sudden Infant Death Syndrome (SIDS).

During the baby’s autopsy, however, State Medical Examiner Thomas Bennett could find no signs of disease or any other underlying health problems that might have factored into death from SIDS.

During the autopsy, Bennett said, they had considered the fact that a 10-day-old infant is rather young for SIDS.

“In any of these cases of a sudden death for a very small child, anyone less than three weeks of age, you have to be very suspicious because usually SIDS doesn’t occur in that first two- or three-week period of life. It can, but it’s very rare,” Bennett said.

Tamara Lass’s death has frequently (and erroneously) been reported as a SIDS death, even though the medical examiner refused to rule it as such. Bennett’s official report lists the baby girl’s cause of death as “undetermined.”

Six-day-old Shane Lass, shown above, was murdered nearly four years after his 10-day-old sister’s cause of death was ruled undetermined.

Less than four years later on February 19, 1992, Teri Lass claimed that her 6-day-old infant son, Shane Alex Lass, was kidnapped from her unlocked, idling vehicle outside the Norwalk post office. Shane’s body was discovered in a ditch outside Norwalk the day after Lass reported him missing. The infant had died of head injuries.

Immediately following Shane’s murder and amidst lingering questions still raised regarding Tamara’s death, Bennett stated he would pull the file of the couple’s first child for review, just to make sure there were no changes needing made to his earlier ruling.

Bennett, however, made no efforts to petition District Court for permission to exhume Tamara Lass’s body. Known throughout the state for his derisive stance over questioned rulings, Bennett reasoned an exhumation wasn’t necessary because he’d found no physical signs of “injury” to the newborn during the autopsy.

He altered nothing in his original report, however, and Tamara Lynn Lass’s cause of death remains classified as undetermined.

Teri Lass was charged with first-degree murder in Shane’s death. Due to pretrial publicity, the case was moved from Warren County to Newton in Jasper County.

The day of opening arguments, criminal defense attorney Alfredo Parrish — a renowned Des Moines litigator known for his superlative ability to raise reasonable doubt with juries — said jurors had already made up their minds about Lass’s guilt and asked the judge to declare a mistrial.

District Court Judge Darrell Goodhue granted Parrish’s motion, and a third location was selected for trial — in Keokuk in extreme southeast Iowa — where jurors unfamiliar with the full scope of Teri Lass’s interminable claims of victimization and ofttimes implausible allegations might be more sympathetic to her most recent contentions.

State Medical Examiner Thomas Bennett finds nothing to indicate Tamara Lynn Lass died of “SIDS.” He rules her cause of death as “undetermined.”

Parrish’s tactics worked once again; despite scores of evidence tying Lass directly to Shane’s blunt force trauma death and the kidnapping note, a Lee County District Court Jury acquitted her March 24, 1993, of murder in her son’s death.

Pending an exhumation and further investigation, she has yet to be charged in her infant daughter’s unsolved death.

Shane Lass’s case also remains open but in name only; Teri Lass cannot be retried in his slaying due to Double Jeopardy laws.

About Tamara Lass

Tamara Lynn Lass was born to Mark and Teri Lass of Norwalk, Iowa, on Saturday, February 20, 1988. She died of undetermined causes 10 days later on Tuesday, March 1, 1988.

Contrary to statements the Lass family provided to news media alleging their daughter died of SIDS (Sudden Infant Death Syndrome), State Medical Examiner Thomas Bennett ruled out SIDS in Tamara Lass’ death. He listed her cause of death as “undetermined,” and stood by his ruling four years later when the Lass’ 6-day-old infant son, Shane, died of blunt force trauma injuries to his head.

Shane’s body, wrapped in a garbage bag and tossed in a ditch, was found on the same day his sister Tamara should have been celebrating her 4th birthday.

Tamara Lass was laid to rest at Norwalk Cemetery in Warren County, Iowa.

Her body has never been exhumed for further exploration into cause of death in the years following her infant brother’s homicide.

There is no statute of limitations on murder.

    No evidence of murder, sudden infant death syndrome, does not usually have an illness associated with it. That is why it is called sudden infant death syndrome.
    There is much about illness and SIDS that we do not know yet. It would be a great travesty of justice to convict these people with no evidence of murder.
    This nott headed pathologist or what ever he is, should know better, rare things do happen, just because they are rare does not mean they never happen.
    It could very well be, these babies inherited a rare malefunktion of the brain that forgets to tell them to breath.
    If there is no evidence of murder, why in the h_ _ _ would any one call it murder.

    • Jody Ewing says:

      Marie, no one here is denying that Sudden Infant Death Syndrome (SIDS) exists. In fact, research shows the rates of SIDS varies tenfold in developed countries from one in a thousand to one in ten thousand unexplained deaths of children less than one year of age. Pathologists ARE trained, however, to recognize and identify one of several very specific underlying susceptibility factors in order to rule cause of death as SIDS. (Search SIDS on Wikipedia or, better yet, explore the topic on the Mayo Clinic’s website or the National Institute of Child Health and Human Development.)

      It takes great courage (and years of experience) for an M.E. to *rule out* SIDS — which is what happened in Tamara Lass’s case — when he could have made things so much easier on himself by attributing her death to SIDS. What I found so unsettling about your comment, however, is your intimation that “these babies inherited” a rare malfunction of the brain “that forgets to tell them to breath.” Did you not see that Tamara’s 6-day-old brother, Shane, was killed by blunt force trauma to the head? That, too, will cause an infant’s brain to forget how to breathe, and Shane’s cause of death wasn’t ruled SIDS, either. These two siblings did not inherit some rare brain malfunction. This is NOT a matter of “personal opinion” (neither mine nor anyone else’s), but is a matter of fact. Look it up under the Freedom of Information Act.

      There are countless loving and decent parents out there who do everything right with new babies, and it angers me that they often have to endure an unwarranted stigma when they lose a baby to SIDS. This stigma wouldn’t exist if not for other types of parents who cite his or her infant’s cause of death as SIDS even when the state’s certificate of death and autopsy report reveal the death was NOT related to SIDS in any way.

      • Chris says:

        This family was told at the hospital that their baby died of SIDS. They were never told anything differently. Years later they requsted her medical records and after bloodwork came back the ER doctor changed the cause of death from SIDS to Sepsis.

  2. mik says:

    From my experience in the Iowa Air National Guard during following these questionable years, it was VERY obvious that every time her husband was deployed, an EMERGENCY of who knows what THIS time happened that required the Air Force to ship his ass home following HER BULLSHIT that she either created or greatly OVER EXAGGERATED. HER character is, and has always been greatly, questionable.

  3. Molly says:

    I grew up 3 blocks away from their house, and she worked for my mother briefly after the second child died. She seemed like just an ordinary person to me, but I was very young. I know they had problems with constant vandalism and harassment up until Rick Forsyth killed six people (2 blocks away) and took the attention off of what happened to Shane Lass. I like to think (if she did do it) it was a postpartum psychosis situation exacerbated by her first child’s birthday, and that maybe she got help.

  4. Prayers for justice for these babies.

  5. Two babies die mysteriously and she’s out there just living her life. Of course the babies aren’t living THEIR lives because someone took their lives from them!

    • Samantha Stevens-Clay, only one of the Lass infants (Tamara) died a mysterious death. Shane was killed by blunt force trauma to the head so there was never any question as to how he died. His case basically remains open in name only because officials are certain they charged and tried the person responsible for his death. Teri may have been found not guilty (which any LE official will tell you is not the same thing as being found “innocent”), but officials are not looking for anyone else in his death because the (plentiful) evidence already proved who did it.

  6. She is on facebook!

    • I can’t think of words bad enough for her if she did kill both of her babies.

    • What concerns me about the first one’s unexplainable death is that even after the medical examiner refused to rule it SIDS, the Lass family continued to lie to others and call it SIDS. (Not like those folks would dare ask to see the death certificate to refute a poor grieving mother’s word.) Just tell people something often enough and it becomes a given truth, right? W R O N G! And then of course there’s Teri’s alleged “rape” (when she was 5 months pregnant with Shane, no less), but when a sister (very wisely) talked her into going to the hospital to report that same-day rape, weeeelll … you already know the rest of that story. No Rape. Not even signs of sex. (Hubby was away in Japan.)

      Yet this same invisible masked intruder allegedly kidnapped and killed her son while she left him unattended in the car despite the slippery stalker’s threat to kill the baby if she told anyone about the [fabricated] rape? No doubt the mischievous sprite also was responsible for the multiple break-ins and fires set at the Lass home. Read Shane’s case summary to learn what detectives had to say about Teri’s carefree demeanor and actions from the moment she reported Shane missing. Not a single tear. Ask some of the expert witnesses about the ransom note with all the piece-by-piece ‘cutting pattern tears’ perfectly matched back to the tape found in the Lass’s home, and those ominous words cut straight out of a ‘True Story’ magazine bearing Teri’s subscription label. Sorry folks, but one can’t blame local or state investigators for this one that got away. Oh yeah, Teri did finally cry. Some verdicts can do that to a person.

  7. Another mom killed her baby there in Norwalk and got away with it if I remember correctly.

    • I’ve lived in norwalk my whole life. I don’t know anyone else in town that killed their baby. She was the only one but there’s been a couple murders

    • Crystal Reynolds Halstead maybe that’s what I remember then. Thanks

    • Yes their was the 2 lass infants but it’s the same mother. There isn’t another mother that killed her baby and got off. That’s what I was saying. Jill was saying there was 2 different moms

      • Kim says:

        Wasn’t there a case back in the mid-2000s where a mom killed her baby by leaving it in a hot car? I was thinking that was maybe somewhere out near Norwalk. She claimed she forgot all about dropping it off at daycare and drove on to work, leaving it to die in its carseat on a hot summer day. She was charged with either first or second degree murder but was either acquitted or found guilty on a lesser charge. Can’t remember the specifics but maybe someone else’s memory might be jogged on it.

    • Crystal Reynolds Halstead You might be remembering two babies b/c of one Lass female infant and one Lass male infant. One just 6 days old, the other 10 days old. About four years apart with deaths.

    • Stacy hagedorn says:

      Heidi Anfinson? Not sure if she lived in Norwalk at one time, her son was found in Saylorville Lake in 1998

  8. Mandie El says:

    I couldn’t read this story, stories of baby’s make me so mad. She will pay for what she did or let happen. May them babies find peace in the loving arms of our Lord.

  9. Jeni Hervey says:

    Kimberly Ann Lawman

  10. Jeni Hervey says:

    She has a Facebook profile. Says she still in Norwalk. Her profile is herself holding a baby! Who on earth would let her around children?????????

  11. I pray someone comes forward. This is
    so sad heart breaking and sad.

  12. Guess he is lucky to be alive with a mom like his, but maybe the apple doesn’t fall far from the tree?

  13. Such a sad story. rest in peace babies

  14. You all need to shut your mouths

  15. Here’s 1 of their kids. Someone said he was charged w impersonating an officer as well as the sexual abuse. Someone inherited mom’s evil.

  16. This lady is a damn psychopath. I find it hard to believe she was ever “shy”. She obviously thrives on attention. All that other sh*t she made up on top of it? How can a jury not convict? I don’t care about reasonable doubt. That goes out the window when u have TWO babies that mysteriously & the other brutally murdered & have been caught lying about a supposed rape. How in the hell did her son survive?? Why? Why not kill him too? Did she figure she could never get away with it again? Why have anymore kids even? Strange that they’re still married. Both share the secret. Sick, sick, sick!!!

  17. She worked at sears credit, just after i left to raise my newborn, couldnt believe she had been aquitted, she is lucky i no longer worked there, I would have loved to have a little chat

  18. Andrea Coco says:

    Everybody knows who did it.

  19. Kari Daly says:

    Wow. Just horrible.

  20. Holly Rice says:

    I knew her as a kid and showed horses with her. She was always so quiet and shy. Can’t believe she turned into a cold blooded killer. Shows that still waters run deep.

  21. I can’t believe that she has a job as a patient care advocate!

  22. Eddi Stearns says:

    My phone was taking forever to load :/

  23. Mark lass and Teri lass

  24. their actual names. She has no profile photo up but her husband does.

  25. What are the names under? I cant find them.

  26. That really is a little o coincidental that they lost two very young kids to murder….wonder what happened that helped her get acquitted?

    • Crazy! Thanks for commenting. Sometimes I wonder how some of those guys can sleep at night. I wanted to be a lawyer growing up and it was always a prosecutor but I know that can be tough too if u are prosecuting someone who is innocent….double edge sword I guess

    • Sorry, posted my response under different comment. Her acquittal was based on “good lawyering” (she had Alfredo Parrish as her lawyer). He’s the best criminal defense attorney in the state (perhaps the U.S.) and can raise reasonable doubt in jurors’ minds despite mountains of rock solid evidence.

  27. Yes their son just got married. I pray they don’t ever leave their future babies with these murders

  28. I agree I’ve seen their pages and they have one son who I think is lucky to be alive and grown how can any parent kill their own child

  29. This horrific lady and her husband are both on Facebook and it is absolutely disgusting the things they post on their walls. They have gone on to live happily ever after while two of their babies lay in a cold snow covered graves. There is NO doubt in my mind that God will be their judge, jury and executioner. Hell bound they are.
