Armstrong was detained at the scene by police officers and later talked with detectives after being read his rights.

“We are thankful for the quick response by patrol officers and detectives to bring this horrible incident to a quick resolution,” said Interim Police Chief Kevin Kolbye. “We continue to work on this case and encourage anyone with additional information to come forward.”

Armstrong is currently being held in the Tarrant County Jail and faces two charges of capital murder and one charge of aggravated assault. Armstrong has no known criminal history. It's not clear if he's obtained an attorney.

Capital murder charges in Texas carry either an automatic sentence of life in prison without parole or the death penalty. Which sentence is sought is determined by prosecutors prior to the start of the trial.
