A mother convicted of killing her young son in 1991 has been denied a new trial.

An appeals court released its ruling Wednesday in the case of Michelle Lodzinski.

Lodzinski was convicted in 2016 of killing 5-year-old Timothy Wiltsey in New Jersey 25 years earlier. She was a suspect early in the case but wasn't charged until 2014 after investigators developed new evidence. She was arrested near Port St. Lucie, Florida, where she had been living.

Lodzinski had initially told police the boy disappeared when they were at a carnival in Sayreville. The boy’s body was eventually in Edison.

Lodzinski’s attorneys argued that prosecutors didn't produce enough evidence to justify the jury's verdict. They also claimed the judge made a mistake when he dismissed a juror during deliberations but didn't declare a mistrial.
