(CNN) -- The man suspected of killing three people and wounding others near Auburn University turned himself in to authorities late Tuesday, authorities said. 

Desmonte Leonard, 22, turned himself in to U.S. marshals at the federal courthouse in Montgomery, said Montgomery County Sheriff D.T. Marshall. 

It was not immediately clear when Leonard would be transported to Auburn. 

Auburn Police Chief Tommy Dawson said Leonard faces three counts of capital murder and two counts of assault. He will be processed into the Montgomery County Jail and "held there for a while," he told reporters. 

"You can't run but for so long," the police chief said. "We were going to pursue until we caught him." 

Dawson also addressed the families of the victims. 

"I know your young men won't be coming home, but hopefully this arrest will give you some closure. It's not over. We're going to continue to investigate this case," he said. 

The development came hours after a small army of law enforcement officers swarmed a Montgomery home where Leonard was believed to be hiding and came up empty-handed. 

Police surrounded and searched the house for more than six hours, spraying "a powerful dose" of tear gas in hopes of flushing out the man. 

They scaled down their efforts at the house Tuesday after they could not find Leonard. 

The officers from local, state and federal agencies looked frustrated, CNN affiliate WFSA reported. 

Police defended the raid at a news conference early Tuesday after reports surfaced that they had gone to the wrong house and used excessive force.
