MODESTO (CBS13) – Police say a man has died after he was attacked by two pit bulls in Modesto.

The incident happened Monday morning along Village Road.

Modesto police say officers responded to help with a medical call after a man was found in a home bleeding and not breathing. The 21-year-old man was soon pronounced dead by medics at the scene.

Investigators believe the man was attacked by two pit bulls owned by the homeowner. Police say the 21-year-old man was visiting and stayed the night with the owner’s permission, but exactly what led up to him being attacked by the pit bulls is unclear.
