A 25-year-old California man has been charged with killing his mother, a beloved elementary school teacher in Burbank.

Burbank Police said they were called to a home on N. Avon Street at about 10 p.m. Tuesday night for an unconscious person. When they arrived, officers and paramedics found the woman and attempted live-saving measures, but she was pronounced dead at the scene.

She was identified as Karyn Lombardo, 57, who lived at the home with her husband and adult son.

Detectives responded and collected evidence revealing that the son, Kyle Lombardo, “caused her death during an altercation in the family home.” He was arrested, charged with murder, and is being held on a $2 million bond.

According to KTLA, Karyn Burbank was a teacher at Bret Harte Elementary School  and had worked in the Burbank Unified School District since 1990, 31 of those years at Bret Harte.

“Her dedication, warmth, and passion for teaching touched many students and colleagues’ lives,” said district superintendent John Paramo in a statement. “Her profound impact and loss on this community will be deeply felt throughout the City of Burbank.”

Paramo said psychologists and social service workers had been made available to students and staff.

“Over the course of her highly accomplished career, Ms. Lombardo touched the lives of thousands of students, parents, and colleagues, who will be mourning this loss in the days to come,” he said.
