“I can tell you right now, we have zero leads,” James Smith, the FBI special agent in charge, told reporters while again asking the public for tips in the rural town of Cleveland, where the shooting took place just before midnight Friday.

The search for the gunman near Houston has grown in scale: Authorities said that by Sunday evening more than 200 police from multiple jurisdictions were searching for Francisco Oropeza, many of them going door to door in hopes of any clues that would lead to the 38-year-old suspect. Local officials and the FBI also chipped in reward money, bringing the total to $80,000 for any information about Oropeza’s whereabouts.

Oropeza is considered armed and dangerous after fleeing the area Friday night, likely on foot. San Jacinto County Sheriff Greg Capers said authorities had widened the search area beyond the scene of the shooting, which occurred after the suspect’s neighbors asked him to stop firing off rounds in his yard late at night because a baby was trying to sleep.

At a Sunday vigil in Cleveland, Wilson Garcia, the father of the 1-month-old, described the terrifying efforts inside his home by friends and family that night to escape, hide and shield themselves and children after Oropeza walked up to the home and began firing, killing his wife first at the front door.

Another of Garcia’s children, 9-year-old Daniel Enrique Laso, was also killed. Garcia said he and two other people had gone to “respectfully” ask Oropeza to shoot his gun farther away from the house, which is on a street where residents say it is not uncommon for neighbors to unwind by firing off guns.

Garcia said he walked away and called the police when Oropeza refused. It was 10 to 20 minutes later when he said he saw Oropeza loading his AR-style rifle while running toward the house.

“I told my wife, ‘Get inside. This man has loaded his weapon,’” Garcia said. “My wife told me to go inside because, ‘He won’t fire at me. I’m a woman.’”

Authorities have said at least five other people who were in the house at the time were uninjured.

During the early hours of the search, investigators found clothes and a phone while combing an area that includes dense layers of forest, but tracking dogs lost the scent, Capers said.

Authorities were able to identify Oropeza by an identity card issued by Mexican authorities to citizens who reside outside the country, as well as the doorbell camera footage. He said police have also interviewed the suspect’s wife multiple times.

Police recovered the AR-15-style rifle that they said Oropeza used in the shootings. Authorities were not sure if Oropeza was carrying another weapon after others were found in his home.

Capers said he hoped the reward money would motivate people to provide information and that there were plans to put up billboards in Spanish to spread the word.

“We’re looking for closure for this family,” Capers said.

By Sunday, police crime scene tape was removed from around the victims’ home, where some people stopped by to leave flowers.

In the neighborhood, an FBI agent, Texas Department of Public Safety troopers and other officers were seen going door to door.One trooper stopped a red truck and asked to look inside before letting the driver continue on his way.

Veronica Pineda, 34, who lives across the street from the suspect’s home, said authorities asked if they could search her property to see if he might be hiding there. She said she was fearful that the gunman had not yet been captured.

“It is kind of scary,” she said. “You never know where he can be.”

Pineda said she didn’t know Oropeza well but occasionally saw him, his wife and son ride their horses on the street. She said the family had lived there about five or six years and that neighbors have called authorities in the past to complain about people firing guns.

The victims were between the ages of 9 and 31 years old and all were believed to have been shot from the neck up, according to authorities. All were believed to be from Hondurus.

Enrique Reina, Honduras’ secretary of foreign affairs and international cooperation, said on Twitter that the Honduran Consulate in Houston was contacting the families in connection with the repatriation of remains as well as U.S. authorities to keep apprised of the investigation.

The FBI in Houston said in a tweet on Sunday that it was referring to the suspect as Oropesa, not Oropeza, to “better reflect his identity in law enforcement systems.” His family lists their name as Oropeza on a sign outside their yard, as well as in public records. Authorities had also previously stated that Garcia’s son was 8 years old, but the father and school officials said Sunday that the third grader was 9.

A total of three children found covered in blood in the home were taken to a hospital but found to be uninjured, Capers said. He said they were staying with family members.

FBI spokesperson Christina Garza said investigators do not believe those at the home were members of a single family. In addition to the young boy, the other victims were identified as Sonia Argentina Guzman, 25; Diana Velazquez Alvarado, 21; Julisa Molina Rivera, 31; and Jose Jonathan Casarez, 18.

Garcia said they had called police five times between the time they asked Oropeza to shoot farther away and when the gunman entered their home. Capers said police got there as fast as they could and that he had three officers covering 700 square miles (1,800 square kilometers).
