Four people were wounded Wednesday morning in a shooting at Timberview High School in Arlington, Texas, that police believe began with a fight.
One person had minor injuries and refused medical treatment, police said at a news conference. Three others were taken to the hospital. Their conditions were unknown.
Police believe three of the victims were students and the fourth may have been a teacher. Two of the victims are believed to have been shot.
The suspect was identified as Timothy George Simpkins, 18. Authorities said he is no longer on the premises. Simpkins is said to be traveling in a 2018 silver Dodge Charger with the license plate number PFY-6260, according to officials.
“This is not a random act of violence. This is not somebody attacking our schools,” Arlington Assistant Police Chief Kevin Kolbye said. “This was a student who got into a fight and drew a weapon.”
Calls came in around 9:15 a.m. about a shooting at the school. Several law enforcement agencies, including Arlington and Mansfield police, responded. The Dallas Field Division of the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) is also on scene.
Although the school is located in Arlington, it is a part of the Mansfield Independent School District.
The district said in a statement that the high school was on lockdown but police have cleared the building. Students were escorted to buses around noon and taken to the Center for Performing Arts to be reunited with their parents.
“Counseling services will also be available for students and parents at the reunification location,” the district said.
One parent told NBC Dallas-Fort Worth that her son is safe and hid underneath a desk as shots rang out.
“He’s just nervous and … in shock,” the boy’s mother said. “He’s just like, ‘Mama, where are you? Just make sure you’re here.’ “
A teacher at the school, Dale Topham, said he was across the hall when the shooting took place and described how students immediately turned the lights off and comforted each other as they hid.
“The students handled it pretty well themselves,” he said. “They hid. They huddled together.”
Timberview is a 17-year-old sprawling 75-acre, 416,000 square foot school about 27 miles southwest of downtown Dallas. It has nearly 1,900 students.
This is at least the second school shooting in the state in less than a week. A Houston high school administrator was wounded Friday after a 25-year-old former student blasted his way through a glass barricade at YES Prep Southwest Secondary, authorities said.
The suspected shooter, who was armed with a rifle, surrendered when he was confronted by responding officers, Houston police Chief Troy Finner told reporters.
