The San Bernardino County Sheriff's Department is seeking a Hesperia man whom they believe murdered a former girlfriend Saturday night.

Neighbors on the 16000 block of Spruce Street called the department Saturday night, shortly before 6 p.m. on Saturday, October 27. Upon arrival at the residence of Yolanda Jarquin, 39, deputies detected a strong smell of natural gas coming from inside the house. Entering the building, deputies found the building full of natural gas and Jarquin dead.

Natural gas is mostly odorless and colorless methane, but other chemicals are added to create a distinct odor so that gas leaks can be safely detected.

The department's Coroner Division has not yet performed an autopsy on Jarquin.

The department's Homicide Detail believes Jarquin was murdered by former boyfriend Oscar Garrido Morales, and a murder warrant has been issued for his arrest.

Morales, who also goes by the names Rene Garrido and Edgar, is a 48-year-old Hispanic man and is described as being 5' 5", 135 lbs. with brown eyes and a shaved head.

The department's Homicide Detail is continuing their investigation. Anyone with information regarding the case is asked to call Detective Neal Rodriguez or Sgt. Frank Bell with the Sheriff's Homicide Detail at (909) 387-3589 or the anonymous WE-TIP line at (800) 782-7463.
