Man With Gruesome Past Sentenced For Arson

He was previously convicted of killing a sexual partner, setting his body on fire and dumping it in a recycling bin.

SAN FRANCISCO, CA — A San Francisco man who was previously convicted of involuntary manslaughter after he killed a sexual partner and set his body on fire in 2011 was sentenced Monday in connection with a 2015 Castro District arson case.

David Munoz Diaz, 27, who has been in custody since his Jan. 21, 2015 arrest, will serve one year of mandatory supervision with electronic monitoring after pleading guilty in August to felony charges of possession of an incendiary device and commercial burglary.

He was also ordered to register as an arsonist and to stay away from the scene of the fire that led to his most recent arrest.

Diaz was arrested in connection with a Jan. 17 fire in the storage room of The Mix bar and a hair salon in the same building in the 4000 block of 18th St. He was originally charged with arson of an inhabited dwelling and
arson of a vehicle.

The arson case was Diaz' second stint in San Francisco county jails following his arrest for the death of 23-year-old Freddy Roberto Canul-Arguello, whose body was found burning in Buena Vista Park on June 10,
2011. A jury found Diaz guilty in August 2014 of involuntary manslaughter but acquitted him of murder in the case.

Defense attorneys argued Diaz had choked Canul-Arguello at the other man's request during a sex act in the park and accidentally asphyxiated him.

Diaz then burned the body, leaving it in a blue recycling bin near the park's tennis courts.

Diaz was sentenced in that case to four years in prison, but because he had served more than three years while awaiting trial he was released shortly after his sentencing date.
