Sheriff's Department

The San Bernardino County Sheriff's Department reported that a man allegedly burned down his ex-girlfriend's house in Fontana.

A woman and her two children escaped unharmed while her 30-year-old ex-boyfriend allegedly burned down her house in Fontana on Halloween night, according to the San Bernardino County Sheriff's Department.

On Oct. 31 at 11:42 p.m., deputies from the Fontana Sheriff's Station received a 9-1-1 call from the victim, who lived in the 9800 block of Arbor Avenue.

The victim reported her ex-boyfriend, Marlon Castro, had allegedly broken into her residence while she was inside with her children. Castro was angry at the victim and allegedly threatened to burn down her home.

The victim was able to grab her children and leave the residence and as she drove off, she saw a large amount of thick, black smoke coming from her residence.

Deputies responded and found the residence completely engulfed in flames and high winds in the area. Deputies cleared the area and looked for potential victims inside the residence. The fire was extinguished by the San Bernardino County Fire Department, but the residence was destroyed.

Deputies conducted a search for Castro with the assistance of Sheriff's Aviation but were not able to locate him. Investigators continued to interview witnesses and residents in the area in an effort to develop leads for Castro.

Then on Nov. 2 at about 11:23 a.m., Castro was seen near the crime scene and taken into custody without further incident. He was transported and booked at West Valley Detention Center on charges of residential burglary, criminal threats and arson.

Anyone with information regarding this incident is urged to contact investigators at the Fontana Sheriff's Station. Callers wishing to remain anonymous are urged to call the We-Tip Hotline at 1-800-78-CRIME (27463) or leave information on the We-Tip website at
