A Common Pleas Court jury on Wednesday found a 28-year-old Butler man not guilty of criminal charges alleging he injured his former live-in girlfriend's 14-month-old daughter in 2019 in Butler Township.

The jury of seven women and five men found Jaime J. Rivera not guilty of felony charges of aggravated assault of a person less than 6 years old and a defendant 18 or older and endangering the welfare of children, and misdemeanor charges of simple assault and recklessly endangering another person.

Judge Timothy McCune found Rivera guilty of a summary charge of harassment and sentenced him to pay a $300 fine and court costs.

The trial began Tuesday with testimony from Jessica Fair, 28, the mother of the toddler, a pediatrician from UPMC Children's Hospital in Pittsburgh who examined the girl and Butler township police. The jury deliberated for about an hour Wednesday after closing arguments were made by Assistant District Attorney Robert Zanella and public defender Kimberly Hudak. Public defender Joseph Smith argued the case Tuesday.

McCune noted that the trial was the first jury trial held in the county during the COVID-19 pandemic. Jurors were seated socially distanced in the public seating area instead of the jury box, and the attorneys and defendant were seated facing the seating area instead of the judge's bench.
