A Jefferson County grand jury indicted three Beaumont men on two counts each of first-degree felony aggravated assault Tuesday, formalizing charges stemming from a July drive-by shooting that sent rifle and handgun rounds into a residential block and struck a van with a woman inside.
The indictments name 22-year-old Cameron Mayes, 21-year-old Keith Malone and 17-year-old Joshua Rebollar, according to 12News. Police paperwork cited by the outlet indicates investigators recovered multiple .556 rifle and 9mm handgun shell casings in the 4100 block of Ector Avenue, where gunfire struck a home three times and hit the driver's door of a nearby van carrying a woman on July 2.
Surveillance Video Pointed Police to a Damaged Silver Sedan
Witness surveillance footage handed over to investigators showed an older silver Nissan Altima with heavy rear-end damage pull up to the residence before occupants got out, fired toward the house, and sped off toward Lavaca Street, the station's report states. That footage gave detectives a specific vehicle to chase down, rather than a vague description, and it set off a rapid technological pursuit across the city.
The Beaumont Police Real Time Crime Center used license plate readers and traffic cameras to track the Altima to the 5000 block of Helbig Road, where patrol officers stopped the car near East Lucas Drive, per the same account. Officers found a black AR-style pistol and a 9mm handgun tucked under the driver's seat, confirming the two types of ammunition recovered at the shooting scene matched weapons in the vehicle.
Fourth Passenger Cleared of Shooting, Held on Separate Warrant
A fourth person in the stopped car, 17-year-old Khailyn Delcambre, was arrested too, but on an unrelated Jefferson County warrant for solicitation of murder, after detectives confirmed he had not been present for the Ector Avenue shooting, according to 12News. His arrest was a separate matter entirely from the charges Mayes, Malone and Rebollar now face.
Following the July 3 arrest of the three men, Mayes was hit with an additional charge of failure to identify as a fugitive from justice, Rebollar was charged with unlawful carrying of a weapon, and police later added charges of engaging in organized criminal activity against all three, the outlet reported. That organized-activity charge suggests investigators looked closely at whether the shooting stemmed from group or gang dynamics, though the indictment itself centers on the two aggravated assault counts per defendant.
Felony Charges Carry Up to Life in Prison
The indictments were filed in Jefferson County's 252nd Criminal District Court, where Presiding Judge Raquel West has served on the bench since January 2015. A firearm-related aggravated assault can be elevated to a first-degree felony carrying up to life in prison and a fine of up to $10,000 — stakes far steeper than a standard assault charge would carry.
Beaumont's Real Time Crime Center, the tool that connected camera footage to the Altima's eventual traffic stop, has grown rapidly since it opened in January 2024 with three staff members. By mid-2026 it had expanded to more than 3,600 integrated camera feeds, a buildout Hoodline detailed in its earlier coverage of a separate Beaumont shooting.
The Ector Avenue indictments put the shooting before Jefferson County's criminal courts as a gun-violence case.
