NEW BRUNSWICK - The prosecutor has rested its case against a mother accused of killing her son 25 years ago and now her defense attorneys have begun calling their witnesses.

Retired Sayreville Police Lt. Robert Dunworth began testifying Thursday in the trial of Michelle Lodzinski. Lodzinski is accused of killing her 5-year-old son Timothy Wiltsey 25 years ago. She initially reported that her son has gone missing from a carnival in Sayreville. She later changed her story to say that he was abducted.

During Dunworth’s testimony, the retired lieutenant seemed to have trouble remembering details. The defense attorneys asked him questions like what time he conducted an interview on a specific date, and he was unable to answer.

"I've been retired for almost 20 years and this was five or six years before I retired, he said. “I've worked a lot of jobs between that time and I've had a lot of time to forget about police work."

When cross-examined by the prosecutor, Dunworth did seem to remember a lot more. 

When asked to describe Lodzinski’s demeanor during the investigation, Dunworth said that she “had a laissez-faire attitude” and seemed to be “enjoying the attention being directed toward her."

Dunworth also noted that Lodzinski didn’t seem to be hysterical or crying when her son went missing. He also testified that he was told by other detectives that Lodzinski suffered a "mental breakdown" after Timmy's disappearance and was taken to the hospital.  He says that when he went to check on her, she had already checked herself out.
