CLEVELAND, Texas (AP) — The search for a Texas man who allegedly shot his neighbours after they asked him to stop firing off rounds in his yard stretched into a second day Sunday, with authorities saying the man could be anywhere by now.

Francisco Oropeza, 38, fled after the shooting Friday night that left five people dead, including an 8-year-old boy. San Jacinto County Sheriff Greg Capers said Saturday evening that authorities had widened the search to as far as 20 miles (32 kilometers) from the scene of the shooting.

Investigators found clothes and a phone while combing a rural area that includes dense layers of forest, but tracking dogs lost the scent, Capers said.

Police recovered the AR-15-style rifle that Oropeza allegedly used in the shootings but authorities were not sure if he was carrying another weapon, the sheriff said.

“He could be anywhere now,” Capers said.

The attack happened near the town of Cleveland, north of Houston, on a street where some residents say neighbors often unwind by firing off guns.

Capers said the victims were between the ages of 8 and 31 years old and that all were believed to be from Honduras. All were shot “from the neck up,” he said.

The attack was the latest act of gun violence in what has been a record pace of mass shootings in the US so far this year, some of which have also involved semiautomatic rifles.

Capers said there were 10 people in the house — some of whom had just moved there earlier in the week — but that that no one else was injured. He said two of the victims were found in a bedroom laying over two children in an apparent attempt to shield them.

A total of three children found covered in blood in the home were taken to a hospital but found to be uninjured, Capers said.

FBI spokesperson Christina Garza said investigators do not believe everyone at the home were members of a single family. The victims were identified as Sonia Argentina Guzman, 25; Diana Velazquez Alvarado, 21; Julisa Molina Rivera, 31; Jose Jonathan Casarez, 18; and Daniel Enrique Laso, 8.

The confrontation followed the neighbours walking up to the fence and asking the suspect to stop shooting rounds, Capers said. The suspect responded by telling them that it was his property, Capers said, and one person in the house got a video of the suspect walking up to the front door with the rifle.

Across the US since January 1, there have been at least 18 shootings that left four or more people dead, according to a database maintained by The Associated Press and USA Today, in partnership with Northeastern University. The violence is sparked by a range of motives: murder-suicides and domestic violence; gang retaliation; school shootings; and workplace vendettas.
