On May 1, 2006, authorities in Conroe, Texas said they responded to a report of a shooting and carjacking in the middle of the night.

It was 1:40 a.m. when investigators said Barry Thomas went out for a late night bite to eat at a local Taco Cabana. Thomas was with his girlfriend when she said an unknown man approached their gray Cadillac and demanded the vehicle. Detectives said the girlfriend immediately jumped out, but Thomas hesitated. Thomas’ girlfriend said her partner was "frozen in fear."

By the time Thomas ran out of his car, it was too late. The suspect allegedly opened fire, striking Thomas twice. Although Thomas was hit, he still managed to run as far as he could.

Detectives said when they arrived on the scene, there was a white Cadillac nearby. It was later determined that the vehicle belonged to the gunman and it had broken down. Earlier in the evening, the suspect and three other friends were in the white car before they stopped at the gas station and they couldn't get it started.

By the time the suspect returned to the gas station, after the alleged carjacking and shooting, the friends did not get in with him – and he took off.

Investigators said a high speed chase ensued.

As for Thomas, he was finally located in a nearby alley by family members, but there was no hope. Thomas passed away from his injuries.

From the witness, who was also the friend of Holmes, confessed he witnessed the murder and gave authorities specific information as to what happened.

Authorities said as for the manhunt, they were soon led to a location in Texas where Holmes was staying. When they arrived, Holmes jumped out of the window and ran. Holmes was eventually taken into custody, put behind bars, but there was a shift in his status. A judge allowed him to post bond. Holmes was back with his family and friends.

It wasn’t long before investigators said Holmes failed a drug test, and was put back behind bars again. But a judge let him out on bond again, authorities added.

In 2008, Holmes cut his ankle monitor, didn’t show up for his trial, and fled. He hasn't been seen since.

Authorities said Holmes may dress as a woman, is known to frequent night clubs, and may have spent time at Mardi Gras. He's known as "Little Glen" or "Glen Davis."

Investigators said if Holmes is found and arrested, he could face the death penalty.

Deputy U.S. Marshal Cameron Welch tells In Pursuit that for Glen Holmes to be on the run this long, "He either has a whole bunch of luck or he has a whole bunch of money."

Holmes is on the shorter side, he only stands 5 feet 4 inches tall and is now in his late 30s. If you have any information on his whereabouts, please submit your tips to InPursuitTips.com or text 1-833-378-7783 (3-PURSUE).
