AUSTIN (KXAN) — Austin police are asking people to be on the lookout for a suspect considered “extremely dangerous” following the murder of his girlfriend.

According to police, Sergio Gomez Herrada, 33, is suspected of killing Francy Vanessa Martinez, 41. He was last known to be in western Bastrop County in the area between Highway 71 and FM 969.

Just before 10 p.m. Sunday, police responded to a home on the corner of Chaparral Trail and Palo Blanco Lane after a 911 call for a “woman down.”

The woman, identified as Francy V. Martinez, 41, was found with “obvious trauma” on her body and she was declared dead at 11:02 p.m. by Austin-Travis County EMS.

“He stabbed her multiple times, more than 20 times,” said Erik Torres, the victim’s brother.

Monday the family gathered to pray outside the home, where Martinez’ nephew first found her in the bathtub.

Torres said he’s been worried about his sister ever since she started dating Gomez Herrada two years ago.

“I was scared, kind of like something bad could happen because I find out he was doing drugs, and he had guns,” Torres said.

Martinez’s red, 4-door Toyota Camry is missing and police are asking the public to be on the lookout for it. It has a Texas license plate FLH-0260.

“We need to locate it and speak to any occupants to determine if they have information related to the crime,” police told KXAN. “Anyone who locates the vehicle is asked to call the police with the location of the vehicle and any occupant description.”

Meanwhile, Gomez Herrada is believed to be using friends and relatives to get around, according to police. You should call 911 and not approach him if you see him.

“We do know that he has obtained a firearm, handgun, and is in possession of that,” said Austin Police Sergeant Eric De Los Santos. “He’s also stated to people that he knows that he will not be taken by the police, so we do consider him extremely dangerous.”

Anyone with information is asked to contact Crime Stoppers at (512) 472-TIPS or text “Tip 103” with your message to CRIMES.
