A man is facing homicide and sexual assault charges after deputies responding to a burglary on Tucson's northwest side Friday morning found a man dead and a woman wounded.

Steven Leska, 46, was arrested on suspicion of murder, domestic violence attempted murder, domestic violence kidnapping and domestic violence sexual assault, said Deputy Ryan Inglett, a Pima County Sheriff's Department spokesman.

Leska was booked into the Pima County jail Friday night, Inglett said.

At 9 a.m. Friday, deputies went to a house in the 1900 Block of West Harran Circle after a 911 call about a burglary that was occurring, said Inglett.

The neighborhood is near West Orange Grove Road and North La Cholla Boulevard.

When deputies arrived, they learned Leska forced his way into the home of a woman who he had a previous relationship with, said Inglett.

Also in the home was James Kozar III, 50, said Inglett. Leska attacked the woman and Kozar, and Kozar was pronounced dead at the scene.

The woman was taken to a hospital with non-life threatening injuries, Inglett said.

Authorities did not release if a weapon was used in the crime.

Deputies found Leska on the property and he was taken into custody. Homicide detectives took over the investigation, and arrested Leska, said Inglett.
