DUARTE, Calif. (KABC) -- The Los Angeles County Sheriff's Department is investigating an altercation in Duarte that left a man dead.

Sheriff's deputies responded to the 2500 block of Maynard Drive just before 7 p.m. Wednesday after receiving a call about a domestic assault.

When they arrived, they saw a man subduing another man on the street and a woman standing near them. The man being subdued was unconscious, according to investigators.

"Paramedics arrived shortly after, rendered medical aid and transported the unconscious male to a local hospital where he was later pronounced dead," said the sheriff's department.

According to investigators, the man who died was the ex-boyfriend of the woman.
