Investigators with the Colleyville fire and police departments have determined the origin of the fire that left a Centennial High School senior dead Tuesday. 


According to a city of Colleyville press release, investigators determined the fire started in the back patio area of the two-story home in the 3500 block of Blue Quail Lane. Pool and other chemicals were being stored in the area, and investigators said they do not believe the fire was intentional.  


The 17-year-old, identified by the Burleson ISD as Tylar Batchelor, was found several hours after the fire was extinguished. 


Fire crews were dispatched at 1 a.m. and arrived minutes later to find the house engulfed in flames, according to reports. Bedford, Hurst, Keller, North Richland Hills and Southlake fire departments responded on mutual aid. 



According to the press release, two men, a woman and a baby were able to exit the house safely. Batchelor was the only one unaccounted for after firefighters were able to control the blaze by 3:35 a.m., the press release read.  


Batchelor's body was discovered at about 7:30 a.m. and turned over to the Tarrant County Medical Examiner's Office. 


Jimerson said Batchelor, an incoming senior, was manager of the CHS soccer team, and easily made friends. 


"She was a great kid," he said. "Well-liked, going into her senior year. The CHS family has truly lost a treasure." 


Jimerson said grief counselors were at the school Tuesday and Wednesday to meet with students.
