Officials have identified the man found dead Saturday morning on an Altadena horse trail near Canon Boulevard.
Victim Marcus Anthony Nieto, 26, had a listed address in West Covina but may have been staying in Azusa most recently, the San Gabriel Valley Tribune reported.
Horseback riders found Nieto apparently shot in the head on Saturday around 8:14 a.m. in the 3800 block of Canon Boulevard.
The investigation is ongoing.
Patch left a message with an official at the Los Angeles County Sheriff’s Department Homicide Bureau Tuesday and will continue to look into the death.
