SAN ANTONIO — Police have arrested a 22-year old suspect they said is responsible for a hit-and-run murder on the city's west side.
Luis Diaz-Quijas faces a murder charge for the death of Christy Cantu. Police said the suspect was an acquaintance of the victim, and that video surveillance helped to build the case against him.
U.S. Immigration and Customs Enforcement (ICE) lodged an immigration detainer on Diaz-Quijas after his arrest. According to ICE, he is from Mexico and in the country illegally.
San Antonio Police officers discovered Cantu's body at the intersection of Rivas and North San Joaquin around 1:00 a.m. Monday.
Police said that Cantu, a woman in her 40s, was intentionally hit by a dark SUV and was dragged for blocks.
Cantu's family was on their way to Chapel Hill Cemetery to pick out a plot for her when detectives called them on Wednesday with news of the arrest.
"We're actually really relieved that part of the nightmare is over," Lenida Cantu-Spurlock told KENS 5 Wednesday afternoon.
"There can be a sense of closure in the sense that we know the authorities have him in custody and we know that he's not a free man and that he can't do it again to someone else."
The initial call came in about a half a mile away on Culebra and Memorial, where an eyewitness saw someone driving erratically and eventually running over a pole near Culebra and North San Joaquin.
An arrest warrant states Diaz-Quijas told police he met Cantu at a club and took her home, where "he said he tried to touch the victim and she pulled out a kitchen knife." According to the warrant, the suspect said she then left the house, but alleges he hit her accidentally later as he was trying to return home.
Police have said a witness told officers Diaz-Quijas followed the victim who was on foot. It appeared the two were arguing. According to court documents, witnesses also told police they saw "a female trying to get away from the vehicle and yelling for help."
"When officers got in the area they began to search, and at one point a couple of streets down, they found a female in the intersection," San Antonio Police Department Officer Carlos Ortiz said.
Surveillance video obtained by KENS 5 shows a person walking through a business parking lot until she pauses at a pole where she appears to be hiding behind. The SUV jumps the curb and runs over the fleeing victim.
"Now we can really just focus on the healing part and moving on, especially for the kids," Cantu-Spurlock added as she wiped away tears and thought of Christy's seven children.
"Now we can let her rest in peace."
