A tragic incident unfolded in a Los Angeles County home Thursday morning, where a 52-year-old man fatally shot his wife and teenage daughter before turning the gun on himself, according to authorities.

Los Angeles County sheriff’s deputies received a call around 8 a.m. reporting an assault involving a deadly weapon at a residence in Lakewood, approximately 20 miles southeast of downtown Los Angeles. The caller, a young woman, informed dispatchers that her father had fired a gun at her and was now unconscious nearby, officials reported.

Upon arrival, deputies encountered the 19-year-old caller outside the home, unharmed. She was subsequently taken in for questioning as part of the investigation.

Inside the residence, deputies discovered a man, identified as Hector Lionel Alfaro, 52, in the den with a gunshot wound to his upper torso. He was confirmed to be the shooter and the father involved in the incident.

The victims of this tragic event were identified as Roxana Rodriguez, 48, and her 17-year-old daughter, Sienna Alfaro, who both lost their lives in the shooting.

Deputies then discovered Alfaro’s 48-year-old wife, Roxana Rodriguez, in a bedroom suffering from gunshot wounds to her torso. In a second bedroom, deputies found the couple’s 17-year-old daughter, Sienna Alfaro, who had also been shot. All three 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.”
