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’s death came just shy of four years after that of his 10-day-old sister, Tamara Lynn Lass.

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 report, and Tamara 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 high profile Des Moines litigator known for his ability to put doubt in jurors’ minds — stated that 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 second trial was scheduled to be held in Keokuk in extreme southeast Iowa where jurors might be unfamiliar with the full scope of Teri Lass’s outrageous claims and [sometimes] implausible allegations.

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; on March 24, 1993, the Lee County District Court jury acquitted Lass of murder charges 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 re-tried in his slaying.
