FULLERTON (CBSLA.com) —A 33-year-old Los Angeles County Sheriff’s deputy appeared in court Tuesday on charges of threatening and assaulting his live-in girlfriend.

According to the Orange County District Attorney’s Office, Alejandro Flores, of Buena Park, has been charged with three felony counts of domestic battery with corporal injury, two felony counts of assault with force likely to produce great bodily injury, and one felony count each of aggravated assault, criminal threats, dissuading a witness by force or threat, and false imprisonment by menace or violence.

Flores is scheduled to return to court next month to enter a plea.

Flores also faces a sentencing enhancement allegation for great bodily injury inflicted during domestic violence and the personal use of a firearm.

Around Oct. 22, 2014, he allegedly hit his girlfriend in her face, which resulted in a broken nose. Authorities said the incident went unreported.

According to city officials, Flores is accused of arguing with the victim about a child’s pacifier on June 28 before he pushed her into a wall.

Prosecutors said Flores hit his girlfriend on top of her head with his fist and then grabbed her neck, which caused her to fall to the ground.

After she attempted to get away from Flores, he dragged her into the kitchen and forcibly held her over the stove. Her hair caught on fire after Flores turned on the gas burner.

When the victim’s hair was extinguished, Flores allegedly threatened her with more violence if she attempted to call the police or left the residence.

According to the district attorney’s office, he allegedly took his girlfriend’s phone and threw it at her leg with enough force to injure her.

When she attempted to scream for help during attacks, Flores is accused of turning up the volume on the television to mask the noise.

Authorities said Flores is also accused of walking into a bedroom to retrieve his off-duty firearm and threatening his girlfriend with the weapon to prevent her from leaving the home.

Officials explained Flores lived with the victim and a child relative under two years of age in Buena Park at the time of the crime.

If convicted as charged, Flores faces 25 years and eight months in state prison.
