A tragic incident unfolded in Los Angeles County on Thursday morning when a 52-year-old man fatally shot his wife and teenage daughter before taking his own life, according to local authorities.

At approximately 8 a.m., Los Angeles County Sheriff’s deputies were dispatched to a Lakewood residence, located about 20 miles southeast of downtown Los Angeles, following a report of an assault involving a firearm. The emergency call was made by a woman who informed dispatchers that her father had fired a gun at her and was now unconscious nearby, as stated by the deputies.

Upon their arrival, deputies encountered the 19-year-old caller outside the residence. Fortunately, she was unharmed and was subsequently taken in for questioning by the authorities.

Inside the home, deputies discovered a man with a fatal gunshot wound to his upper torso lying on the floor in the den. The individual was later identified as Hector Lionel Alfaro, 52, who was confirmed to be the shooter.

Tragically, the investigation revealed that Roxana Rodriguez, 48, and her 17-year-old daughter, Sienna Alfaro, were the victims of this devastating act.

Further examination of the scene led deputies to find Roxana Rodriguez in a bedroom, suffering from gunshot wounds to her torso, while in another bedroom, they located Sienna Alfaro, also fatally shot. All three individuals were pronounced dead at the scene.

“Through investigation, Homicide Investigators learned gunshots were heard within the residence by Alfaro’s 19-year-old daughter while she was asleep,” the sheriff’s department said in a statement obtained by FOX11 Los Angeles. “Alfaro then appeared near her armed with a handgun and shot at her several times; however, she was not struck by the gunfire. Alfaro then shot himself while standing near his 19-year-old daughter.”

Two firearms were recovered from the home.

Authorities have not identified a motive. The investigation remains ongoing.

“Our hearts are broken as we share the tragic loss of a loving mother and her daughter, whose lives were taken by an act of unimaginable violence,” wrote Andrew, the husband to the couple’s eldest daughter Desiree, in a GoFundMe post. “This devastating loss has left behind their surviving children, who are now facing the world without the people who meant everything to them.”

Sienna’s soccer teammate, Hazel Ferman, remembered her friend as “a ray of sunshine” at a candlelight vigil on Saturday, according to KABC-TV.

“She’s a very jolly person,” Ferman said. “Her smile would bright up the room. Her energy was just out of this world, man like she would walk in, even though she’s a shy girl, when she would smile is like everybody knew that we just connected.”
