After the shooting, a scanner listener spotted the vehicle and called it in. After a chase the individuals were caught, both were heavily armed and wearing body armor.
Here is the press release form the City of Tyler (interesting, this press release does not mention the body armor):
"Texas Department of Public Safety Trooper Steven Stone, 29, was shot Wednesday night, March 22, 2006 around 9:20 p.m., when he made a traffic stop on Texas Highway 31 just east of Farm-to-Market Road 2908.
Trooper Stone pulled over Ramon Ramos, 37, and Francisco Saucedo, 38, both of Tulsa, Okla., for a speeding violation.
After advising the driver (Ramos) of the truck the reason for the stop, Trooper Stone developed probable cause to arrest Ramos. During the arrest Ramos pulled a 9 mm handgun from his waistband and began firing the weapon point-blank at Trooper Stone. The passenger (Saucedo) and Ramos then began firing multiple rounds at Trooper Stone striking him several times.
Tyler Police received a call at 9:39 p.m. from a citizen who had been monitoring scanner traffic and thought the suspects had just pulled into the La Michoacana Meat Market. The caller described the vehicle as a dark truck with a Hispanic driver.
When officers arrived in the area, the suspect vehicle fled from officers eastbound on Commerce Street. The passenger started firing several rounds at officers that were pursuing them. Several Tyler police cars were hit by gunfire and some shots went into the passenger compartments only inches away from officers. The pursuit traveled east on Commerce to Loop 323, then to Texas Highway 64, where the suspects crashed into another vehicle that had pulled to the side of the roadway for emergency vehicles.
Investigators believe the suspects fired 75 to 100 rounds during the pursuit and Tyler officers fired 35 rounds during the chase.
Officers located several weapons inside the suspects vehicle including a Norinco SKS assault rifle, a Tec 9 9 mm, a Beretta 9 mm and a .22- caliber handgun.
Ramos and Saucedo have been released from the hospital into the custody of the Smith County Jail, where they’re being held on 14 counts of aggravated assault/with a deadly weapon on a public servant and an U.S. Immigration and Customs Enforcement hold. State District Judge Jack Skeen set both men's bonds at $23 million on each subject."
