Texas Man Luis Angel Montes Still on the Run After He Tracked Girlfriend's Car for Months and Murdered Her

A Texas man who allegedly murdered his girlfriend after months of tracking her vehicle was still on the run as deputies are still on the lookout for him.

The 35-year-old Texas man, Luis Angel Montes, reportedly put a GPS device on the vehicle of her girlfriend, Camerina Trujillo Perez, 38, according to a Crime Online report.

A witness reported the incident in an affidavit. Authorities also noted that Montes saw Perez hug and kiss another person at a local supermarket.

Authorities said that the couple was last seen together on January 24 while family members decided to report them missing on January 25.

During the first missing person's case, officials said that Perez's vehicle was reportedly seen on January 27 traveling north through Temple.

They noted that detectives are looking at the tip but not ruling the possibility that her vehicle could be anywhere in the state of Texas or beyond.

A witness told in an affidavit that Montes looked sad and upset after seeing the incident with Perez kissing another guy. However, the witness noted that the Texas man did not appear angry or did not make any threats towards the two, according to a KXAN News report.

Police said that Montes called Perez repeatedly after the incident and met with his girlfriend at a bank parking lot in Pflugerville.

That was when Montes "repeatedly assaulted" Perez to the point that caused her death, according to the affidavit.

Surveillance camera footage from the bank showed that there was a significant amount of blood that was seen pooling between the two vehicles.

A resident who lives next door to the bank where the reported crime happened said that it is absolutely shocking that somebody got murdered next door.

Angel Tucker said one does not think that it would happen in your neighborhood.

Perez's daughter told police that her mother and Montes had been dating for some time, according to an arrest warrant.

Perez's daughter added that Montes had told her in the past that if Perez tried to leave him, he would kill himself or "do something stupid," according to a CBS Austin News report.

The daughter added that they believed Montes had been tracking her mother for months, adding that they also believed that Montes had put a tracking device on Perez's car as he would show up to places she was at unannounced.

Meanwhile, officials are hoping the public could assist in the investigation, noting that if individuals locate the blue 2014 Chevrolet Sonic with a Texas license plate FZH-0400, they should call authorities.

Investigators are also looking for a black 2014 Toyota Tundra with a Texas license plate CVH-2575, believing that the vehicle could also be involved in the couple's disappearance.

Montes reportedly drive Perez's car with her body in the vehicle, with investigators believing he headed to Lake Pflugerville to get rid of or hide evidence.

Travis County Sheriff Sally Hernandez said they are doing everything to find Montes.
