A 20-year-old man has been arrested for killing his girlfriend after he allegedly stabbed her and repeatedly ran over her with his car while she was on the phone to her mother.
Joshua Garcia was charged with murder after his 19-year-old girlfriend Erin Castro was found lying on a road in San Antonio,
Texas in the early hours of Sunday morning.
The victim had frantically called her mother to tell her Garcia had stabbed her in the neck and was refusing to let her out of his car after they had a fight.
Castro's mother quickly called 911 and authorities were able to trace the teenager's phone.
The victim's mother stayed on the phone with her daughter until medics arrived.
Garcia's brother told investigators he witnessed the crime after his brother asked him to drive to the location because he was having trouble with Castro, according to court documents obtained by
KENS5.
He said he saw his brother and his girlfriend arguing outside the car before Garcia ran over Castro. He then allegedly put the car into reverse and ran over her again.
Garcia then allegedly got out of the car and kicked his girlfriend's injured body.
Police said Garcia and his brother then left Castro's body and drove home.
Garcia had claimed that Castro assaulted him when he was driving.
He told police he was scared of what would happen if Castro called authorities.
Castro was found by EMTs with what they described as catastrophic injuries over her entire body.
She died at the scene.
