Student taken into custody hours after Texas school shooting

An 18-year-old student opened fire during a fight at his Dallas-area high school on Wednesday, injuring four people and then fleeing before being taken into custody hours later, authorities said.

Timothy George Simpkins was taken into custody without incident and charged with multiple counts of aggravated assault with a gun, the Arlington Police Department tweeted.

One person was in critical condition, another was in good condition and a third person was treated for minor abrasions and was scheduled to be released from the hospital Wednesday afternoon, police said. A fourth person was hurt but did not require treatment at a hospital. Police said earlier that three of the four injured were students.

The shooting at Timberview High School, which is in Arlington but belongs to the school district in neighboring Mansfield, stemmed from a fight that broke out in a classroom, Arlington Assistant Police Chief Kevin Kolbye said at news conference before Simpkins' arrest.

“This is not a random act of violence,” he said. “This is not somebody attacking our school.”
