Probable cause affidavits for the arrests of two suspects in the Alamo McDonald’s parking lot killing on Tuesday indicate the victim was threatened with murder or a beating prior to a fatal meeting there.

Those documents identify the victim as Raul Cantu Jr.

He was shot and killed at approximately 11:47 p.m. that day at the eatery at 1018 W. Frontage Road.

Alamo police thus far have arrested three people: Jose Alberto Jimenez Jr., a 26-year-old resident of Pasadena, Texas, 23-year-old McAllen resident Alberto Angel Medina and 44-year-old Alamo resident Christina Louise Montemayor. All three remained jailed in the Hidalgo County Adult Detention Center.

Meanwhile, Alamo police announced Friday afternoon that they are seeking a fourth suspect in the case who they say should be considered armed and dangerous.

Carlos Alfredo Rivera Jasso, 31, is sought on an active murder warrant.

Police said he stands 5 feet, 7 inches tall and has black hair. He has multiple tattoos, including a skeleton hand tattooed on his right hand.

Investigators also said he is an active Tri-City Bomber gang member.

Police spokesman Jacob Garcia has said previously that investigators believe the shooting is gang and drug related.

When authorities arrived at the McDonald’s that night they found Cantu dead with multiple gunshot wounds.

“During the review of the McDonald’s camera footage, Investigators observed Raul Cantu Jr. walk through the parking lot towards frontage road where he made contact with two male subjects,” the affidavit stated. “Investigators observed Raul Cantu Jr. interact with the subjects on what appeared to be a transaction.”

Then a man — Jimenez — arrives in a blue Ford Fusion.

“One of the male subjects later identified as ‘Los’ struck Raul with both his hands, while the second subject punched Raul Cantu Jr. with his left hand and pushed Raul Cantu Jr.,” the affidavit stated.

That’s when Medina pulled out a black handgun from his waistband and shot Cantu twice in his upper torso, according to the affidavit.

That document says that’s when the men were seen leaving in a brown 2013 Chrysler 200, which investigators learned was driven by Montemayor — Cantu’s girlfriend.

Alamo investigators were familiar with Montemayor from “previous encounters” so they called her and asked her to come to the police department to provide a statement.

She complied and initially told investigators she went to McDonald’s to get food for her kids, according to the affidavit.

However, she recanted and said she went there because “Los” was going to give Cantu $100.

She also told police she picked up “Los” and Medina at 1301 19 ½ St. in McAllen and drove them to the McDonald’s to meet with Cantu.

She also claimed to not know the men, according to the affidavit. However, after the shooting she drove “Los” to the Motel 6 located at 700 W. Expressway 83.

“The defendant stated she heard shots being fired but did not see what happened,” the affidavit stated.

Meanwhile, investigators responded to that address — which was the scene of a homicide in July in McAllen — and arrested Medina.

Garcia, the police spokesman, previously said a murder occurred at the residence and The Monitor confirmed through affidavits that the murder he is referring to occurred on July 18.

In that case, McAllen police have charged Carmen Lizeth Valdez, 31, of McAllen, and 30-year-old Donna resident Nathan Antonio Germain for the fatal shooting of 36-year-old Donna resident David Martinez. Both Valdez and Germain remain held in the Hidalgo County Adult Detention Center.

It isn’t immediately clear whether the Alamo and McAllen cases have anything to do with each other.

And Medina — who was arrested at that McAllen residence — declined to provide investigators with a statement.
