TALLAHASSEE, Fla. (AP) — Officials say the roommate of a Florida gay rights activist strangled him and dumped his body in a rural Florida landfill.

A grand jury indicted 37-year-old Steven Yinger last week. He’s being held on multiple charges including first-degree murder in the death of Jorge Diaz-Johnston.

Yinger was rooming with 54-year-old Diaz-Johnston at the time of his death.

Diaz-Johnston, the brother of former Miami Mayor Manny Diaz, was last seen alive Jan. 3, reported missing Jan. 7 and his body was found Jan. 8.

Diaz-Johnston was an advocate for marriage equality.
