SALIDA, COLORADO — The co-owner of a Colorado crane company that once employed the Waffle House shooting suspect said they urged the Secret Service to try to help him after he was arrested at the White House last year.



Police say Travis Reinking, 29, killed four people and wounded four others with an AR-15 rifle Sunday as he stormed the restaurant in Nashville wearing nothing but a green jacket.



But Reinking had exhibited erratic behavior for years before the shooting. Darlene Sustrich, who co-owns a Colorado crane company where Reinking once worked, said they got a call from the Secret Service after he refused to leave a restricted area at the White House last July.



"We told them, 'Hang onto him if you can. Help him if you can,'" Sustrich said.



Federal officials did not immediately respond to a request for comment.



Reinking has been charged with four counts of criminal homicide. And a tweet from the Metro Nashville Police Department said he also faces four counts of attempted murder and one count of unlawful possession in the commission of a violent felony.



Davidson County Sheriff Daron Hall said Tuesday that Reinking has been "compliant" and "cooperative" since he was transferred to the jail late Monday after he was captured near the apartment where he lived. Reinking is wearing a vest known informally as a "suicide smock" and will remain under close observation at a maximum-security facility in Nashville.



An attorney listed as Reinking's lawyer did not immediately respond to an email seeking comment.



Meanwhile, the man who snatched the rifle away from the gunman during the shooting told Tennessee lawmakers Tuesday he faced "the true test of a man," drawing a standing ovation during his brief address. As the state House hailed him as a hero, James Shaw Jr. said he acted to save his own life early Sunday and saved others in the process.



"I never thought I'd be in a room with all the eyes on me, but you know, I'm very grateful to be here," Shaw told House members. Shaw said he has gone to see some of the shooting victims in the hospital and they all remembered him. He apologized to the people whose loved ones died in the attack.
