Man Wanted For Alleged Murder Of His Girlfriend Had Been Tracking Her For Months, Authorities Say

A Texas man wanted by authorities in the killing of his girlfriend had allegedly tracked her for months before her death, according to new court records.

The Travis County Sheriff’s Office issued a murder warrant for Luis Angel Montes, 35, earlier this month in the death of his girlfriend Camerina Trujillo Perez, after Montes went on the run.

As law enforcement authorities continue to try to track Montes down, new disturbing details are emerging about what investigators believe led to the murder.

Perez’s daughter told investigators her family believed Montes had been tracking Perez’s car for months with a GPS tracking device because he would always show up unannounced wherever she was, according to affidavit obtained by KEYE-TV.

Montes also allegedly threatened Perez that “if she tried to leave him, he would kill himself or do something stupid,” her daughter told authorities.

Investigators believe the couple reached a breaking point on Jan. 24 when Montes allegedly saw Perez at a grocery store, hugging and kissing another person, according to the affidavit, also obtained by KXAN.

A witness described Montes as looking sad and upset but said he “did not appear angry and did not make any threats” toward Perez.

However, authorities say cell phone data shows that later that day Montes repeatedly called Perez and the two met at a bank.

The pair are seen in surveillance video arriving at the bank and getting out of their respective vehicles, but then the exchange turned violent, according to the affidavit.

Montes “repeatedly assaulted” Perez “to the point that caused her death,” leaving a large pool of blood between the two cars, authorities said.

Investigators said Montes drove Perez’s car “with her lifeless body still in the vehicle” away from the bank. Authorities believe he may have headed to Lake Pflugerville to dispose of the body or conceal evidence before he disappeared, court documents suggest.

“This is a horrible outcome, and my heart goes out to Camerina’s friends and family. We are doing everything we can to find Luis Montes and bring justice to her loved ones,” Sheriff Sally Hernandez said, while announcing the warrant.

Kristen Dark, the senior public information officer for the Travis County Sheriff’s Office, told Oxygen.com last week that authorities had not located Perez’s body and were still searching for Montes.

Anyone with information about his whereabouts is urged to contact law enforcement authorities.
