The Fresno County Sheriff's Office arrested 36 year old Angel Gaytan from a home in Southeast Fresno on Wednesday.
Detectives worked with the US Marshals Service to track him down after identifying him as a suspect last week.
On February 18, authorities responded to Chestnut and Harvard, where they found 37-year-old Dominic Greco dead.
Investigators later determined that Greco's death was a homicide but details have yet to be released.
