Authorities said they have confirmed that a possible sighting in College Station of an escaped inmate was not Arcade Joseph Comeaux Jr.
Comeaux escaped Monday and was serving a life sentence for aggravated sexual assault of a child in Brazos County.
College Station police said they received reports from a resident who thought they saw Comeaux at Taco Cabana Tuesday morning, but after further investigation, they discovered it was not him.
As a result of the sighting, College Hills Elementary School was placed on lock down, officials said.
All schools in Bryan and College Station remained on alert and staying in touch with local police, officials said.
Texas A&M University sent students and staff a message through their emergency notification system that there was a "prison escapee suspected in CS area, exercise caution, monitor local media, report sightings to local police."
Bill Turner, Brazos County district attorney, said Comeaux was accused of two aggravated assault cases in Brazos County in June 1997, and was convicted of the first charge and sentenced to 99 years in prison in June 1998. In both cases, the children were less than 14 years old, he said.
Comeaux's victims had been notified of his escape, Turner said.
"We asked police to keep a close eye on the residences," he said. "We're taking every precaution necessary."
Turner said authorities will continue to keep a close eye on the victims until Comeaux is located.
The guards were transferring Comeaux from a prison unit in the Huntsville area to one in Beaumont when he pulled out a gun and told the guards to stop the vehicle, said Michelle Lyons, a spokeswoman for the Texas Department of Criminal Justice.
The guards were held hostage temporarily, she said. Before Comeaux fled on foot, he took one of the officer's grey uniform and the officers' weapons: 12-gauge shotgun and two semiautomatic pistols with him.
Comeaux is described as a black male, about 6 feet tall and 200 pounds.
Anyone who believes they have seen Comeaux should call 911 or Crime Stoppers at 1-800-832-8477.
