Authorities have credited the arrest of the Texas mass shooting suspect, 38-year-old Francisco Oropesa, Tuesday evening to a tip submitted through the FBI tip line. 

"Somebody got a tip," San Jacinto County Sheriff Greg Capers said during a press conference Tuesday. "It was a multi-jurisdictional operation, to say the least. DPS, C.I.D. U.S. Marshals, FBI. We had a tag team, and they all meandered over there and found out that that tip to be true."

Authorities said the tip about the suspect's location came in at 5:15 p.m. Approximately 75 minutes later, Oropesa was taken uninjured into custody in the Cleveland area.

Oropesa (also spelled "Oropeza") is a Mexican national who is suspected of fatally shooting five of his neighbors before midnight on April 28.

Texas Gov. Greg Abbott's office and multi-county crime stoppers announced a combined $55,000 to a tip that resulted in Oropesa's arrest.

FBI Special Agent in Charge James Smith announced Sunday an additional $25,000 FBI reward in connection with the investigation, increasing the total reward amount to $80,000.

Authorities said during the press conference the individual will be paid the sum for their assistance.

FBI ASAC Jimmy Paul said the FBI was "extremely delighted that the suspect was captured" and also praised the "courage and bravery" of the individual who submitted the tip.

"The tip for the suspect's location came in through the FBI tip line. And we just want to thank the person who had the courage and bravery to call in the suspect's location," Paul said.

The suspect was arrested in Cleveland, approximately 20 miles from the home where the initial shooting took place. The Border Patrol’s elite BORTAC unit apprehended the suspect without incident.

"He was caught hiding in a closet underneath some laundry. They were effective [and] made the arrest. He is uninjured, and he is currently being taken to my facility in Cold Springs," Capers said.

Investigators said the shooting on April 28 was allegedly prompted by neighbors requesting Oropesa move further from their home as he was firing a rifle in his yard. 

Members of the rural community often fire weapons outside their homes, but the neighbor expressed frustration as their child was having trouble sleeping.

Oropesa then allegedly charged at the neighbors, reloaded his AR-15 and fired the weapon, hitting four adults — Sonia Argentina Guzman, 25; Diana Velazquez Alvarado, 21; Julisa Molina Rivera, 31; and Jose Jonathan Casarez, 18. They were declared deceased at the scene.

Daniel Enrique Laso Guzman, age 9, was also struck. He was airlifted to a hospital, where he was declared deceased.
