(Trends Wide) — As Texas investigators race to find the man accused of fatally shooting 5 people, including a mother and her 9-year-old son, in a Texas home, US Border Patrol agents are keeping an eye on the fugitive in case he tries to flee to Mexico, a law enforcement source familiar with the investigation told Trends Wide.

Authorities on Monday released new images of the fugitive, identified by investigators as Mexican citizen Francisco Oropesa, on a wanted poster. The poster shows several of the suspect’s distinctive tattoos and warns that he is “armed and dangerous.”

Oropesa, 38, is accused of carrying out the massacre last Friday after being asked to stop firing his rifle near the home of a neighboring family in Cleveland, a city of about 8,000 northeast of Houston, in Texas.

The victims, all of Honduran nationality, were identified as Sonia Argentina Guzmán, 25, and her son Daniel Enrique Laso Guzmán, 9; Diana Velázquez Alvarado, 21 years old; Julisa Molina Rivera, 31, and José Jonathan Cásarez, 18.

An FBI agent said over the weekend that investigators have “zero leads” on Oropesa’s whereabouts.

Authorities are urging the public to come forward with any information about the case and have dedicated substantial resources to tracking down the suspect, including more than 250 law enforcement officers and a collective reward of $80,000 for tips leading to his arrest.

The hefty reward is advertised on billboards in Spanish, authorities said. Media outlets across Mexico are also being contacted if he is already there, the police source told Trends Wide on Monday.

Although Oropesa’s current immigration status is unknown, the suspect entered the United States illegally and has been deported by immigration officials at least four times since 2009, said the ICE source, who identified the suspect with the name of Francisco Oropesa Pérez Torres.

He was first removed by an immigration judge in March 2009 before being deported again in September 2009, January 2012 and July 2016, the source said.

It is not known how long Oropesa has been in the US since his last deportation, according to the source.

This is how the massacre unfolded

Wilson Garcia, whose wife and son were killed in the shooting, told Trends Wide that 15 people gathered at the Cleveland home, including friends and godparents who had come to help his wife get ready for a church event.

About 10 to 20 minutes before the massacre on Friday, Garcia and two others had walked to Oropesa’s patio to ask her to stop shooting so close to her house because Garcia’s baby was sleeping, she said. Oropesa had been asked to shoot across his property, the father said.

The suspect refused and Garcia said he would call the police.

“We went in and my wife was talking to the police, and we called five times because he was being more threatening,” Garcia recalled.

“We saw him, he was coming off his property and he cocked his gun,” the father said. “I told my wife to come in because she got her gun ready and she could come threaten us. Then my wife said: ‘You come in, I don’t think he’s going to shoot me because I’m a woman, I’ll stay here at the door’”.

Shortly after, the attacker broke into Garcia’s home. He first shot his wife, Sonia Argentina Guzmán, in the driveway before killing three other adults and García’s son, Daniel Enrique Laso Guzmán, his grieving father said.

“One of the people who died saw my wife fall to the ground,” Garcia told Trends Wide.

“He told me to throw myself out the window because my children were already without their mother. So one of us had to stay alive to take care of them. She was the person who helped me jump out the window.”

The woman who helped Garcia flee did not survive, he said.

“Two people who died were protecting my 2 1/2-year-old daughter and my 1-month-old son,” Garcia said through sobs. “They protected him with a lot of clothing so the killer wouldn’t kill him too. So imagine what we’re feeling right now. It was horrible”.

When police arrived, they found the victims had been shot “almost execution style” at close range above the neck, San Jacinto County Sheriff Greg Capers told local media.

Authorities got to the scene as quickly as they could, Capers said. But his small force covers a large county, he said, and the house is about 15 minutes from the city.

“I feel like a part of me has gone with her”

As the families of the victims mourn their losses, Argentina Guzmán’s loved ones struggled to put their grief into words when speaking to Trends Wide.

His brother, Germán Guzmán, said his pain is “inexplicable.” He added: “It’s hard to know that people who are very close to you are gone, very hard.”

“I feel like a part of me has gone with her. I feel like a part of my heart is broken,” said her mother, Francia Guzmán.

“With God’s permission, she will return in a coffin so that I can say goodbye even if she never answers, even if she can no longer tell me anything,” said the mother.

Honduran officials have said they are preparing to repatriate the remains of the victims.

“The Government of Honduras deeply regrets the loss of these valuable lives and accompanies all their loved ones in their pain. We demand that the pertinent authorities arrest the perpetrator of this terrible act and apply the full weight of the law,” the Honduran Foreign Ministry said in a statement.

“The only thing I want is for them to be returned to me so that they can rest where they were born, so that they can rest forever and be in a place where at least I can bring them a flower,” said Francia Guzmán.
