Tucson police officers are searching for a man who allegedly killed a 55-year-old man at his west-side home Monday night, police say.
Andrew Gallardo called police at about 6 p.m. to report an unwanted person refusing to leave his home in the 100 block of South Grande Avenue, near Congress Street.
When officers arrived, they entered Gallardo's home where they found him unresponsive with obvious signs of blunt-force trauma, a Tucson Police Department news release said.
Paramedics pronounced him dead on scene.
Detectives determined Gallardo was in a physical altercation with the unknown man in the front yard of his home.
Police are attempting to identify the man. He's described as being in his 30s to 40s with short, dark hair with tattoos on his arms and neck.
The investigation is ongoing. Anyone with information is asked to call 88-CRIME, an anonymous tipster line.
