PORTAGE, Ind. (AP) – Police in northwest Indiana continue investigating the death of a 40-year-old man who the coroner says was apparently killed by a pit bull.

The Post-Tribune of Merrillville and The Times of Munster report Porter County Coroner Chuck Harris says Edward Cahill suffered multiple severe bite injuries to his arms and face that resulted in massive blood loss. He says no one witnessed the attack in Cahill's home in Portage, 50 miles west of South Bend.

Cahill's girlfriend arrived home around 8 p.m. and discovered Cahill on the floor unresponsive. He was pronounced dead at the scene.

Police say two pit bulls were in the home. Harris says one dog demonstrated aggressive behavior when it was given a bone. That dog was removed from the home.

Police continue their investigation.
