NACOGDOCHES, TX (KTRE) - Detectives with the Nacogdoches Police Department are seeking the public's help in locating the 19-year-old man suspected of fatally shooting 24-year-old Dominique Brooks on Dec. 5.

According to a press release, Marcus Shwayne Isaac, 19, is wanted for murder. He is described as being 5-foot-3 inches tall and weighing about 130 pounds. He has brown eyes and black hair.

"Isaac is known to frequent the Nacogdoches and Center areas," the press release stated. "He was last seen driving a 2008 Mercury Grand Marquis with the license plate DVS-2642.

The fatal shooting incident occurred on Railroad Street on the evening of Dec. 5. According to a previous East Texas News story, Isaac had been involved in an altercation with a resident of the house where the shooting occurred.

"The suspect returned to Railroad Street armed with a handgun and began firing at the residence as he was walking down the street, in retaliation," a press release stated.

Brooks and several other people were on the porch of the home when she was shot in the chest. She was rushed to Nacogdoches Memorial Hospital, where she later died.

The press release said that Brooks wasn't involved in the altercation that occurred at the residence before she was shot.

Bystanders at the scene told East Texas News that the suspect, who was later identified as Isaac, fled the scene after Brooks was shot.

Back in November 2012, Isaac turned himself in to the Nacogdoches Police Department on a Center Police Department warrant for evading arrest. Center Police Det. Joey Haley told the East Texas News that Isaac was a person of interest in a series of car burglaries and thefts that occurred in Center.

Haley told the East Texas News that Isaac run around with a group of about three or four young men, and that Isaac has had numerous run-ins with the law, including several juvenile cases.

While they were investigating the series of car burglaries and thefts, Haley and his partner found a wooded area with numerous trails in and out of it in the part of Center where the burglaries have been occurring. A search of the wooded area revealed a Mazda car that had the kind of damage that indicated it had been stolen, Haley said. Their hunch was right; the car had been stolen from Nacogdoches.

Another recovered stolen vehicle had been set on fire and burned to its rims, Haley said. The Center PD detective said the series of crimes started in late September and continued through early November of 2012.

When Haley and his partner approached Isaac to bring him in for questioning, Isaac saw them and immediately began walking in the other direction. Haley said Isaac kept going after he told him to stop, and his partner started chasing the 17-year-old. Isaac ran from them, jumped an 8-foot fence, and vanished into a nearby wooded area.

In November 20013, the Center Police Department released new details in the case. Isaac was wanted in connection to an Oct. 24, 2012 incident in which two vehicles were burglarized at East Texas Medical Clinic.

A press release issued at the time stated that CPD detectives were called out to process the scene, but "had no suspects and little to go on." However, they did collect blood samples from where the suspect had cut himself while breaking into one of the vehicles.

After the blood was submitted to the Texas Department of Public Safety Crime Lab, it came back as a positive match to Isaac.

"If anyone knows the whereabouts of this suspect, contact the Nacogdoches Police Department at 559-2607 or Nacogdoches Crime Stoppers at 560-INFO (4636) or on the web at ," the press release stated. "Never attempt to apprehend a wanted fugitive yourself. Contact law enforcement. All fugitives should be considered armed and dangerous."
