The Trenton Police Department said autopsy results have ruled the death of a woman and a child  found dead in a restaurant parking lot earlier this year as accidental.

As we previously reported, the department began investigating in July after 24-year-old Elizabeth LaFolett and her 11-month-old daughter Shannon Jeannoutot-LaFolett were found dead in a running vehicle in the parking lot of McDonald’s located at 1861 E. 9th St.

Police Chief Tommy Wright said autopsy results came back last week and ruled both deaths as accidental.

“The daughter was a heat-related death and the mother was an overdose related death,” Wright said.

Wright said authorities have looked into who may have provided the substances that contributed to the deaths.

“We’ve looked into some of who could potentially have provided the medications that were taken but at this point we don’t have any definitive evidence to demonstrate that but there would be nothing more that we would like then to be able to pin something on a dealer who provides the poison for a community,” Wright said. “They were legal substances.”

Wright said toxicology results usually take 6 to 8 weeks so the length of time it took to get the results back was not out of the ordinary.
