CARRICK, Pa. – Authorities say a man accused of fatally stabbing and shooting a university professor and killing the victim’s dog inside the Pennsylvania home they shared remains at large.

Joseph Martin is charged with criminal homicide in the death of 71-year-old Ricardo Tobia. His body was found Saturday at the Carrick home by police conducting a welfare check after Tobia’s sister said she couldn’t contact him.

Tobia was a voice instructor at Point Park University in Pittsburgh. He was a professor there for 35 years and worked part time.

An autopsy showed Tobia suffered multiple stab wounds to the torso and neck, a laceration wound of the abdomen and a gunshot wound to the head. Tobia’s beagle had its throat cut and was shot in the head.

Authorities say the 35-year-old Martin has long dealt with psychiatric issues.
