Report: Manziel threatened to kill his ex-girlfriend and himself

When Johnny Manziel was investigated for an altercation with his ex-girlfriend last week, part of the police report said Manziel's ex-girlfriend was concerned about his well being, but the initial report never explained why.More troubling details have emerged, including an accusation by ex-girlfriend Colleen Crowley that Manziel hit her, dragged her by her hair and threatened to kill her and himself. Crowley said Manziel told her "shut up or I'll kill us both," WFAA reported. WFAA cited anonymous sources, who shared details of Crowley's affidavit, in its story."He grabbed me by my hair and threw me back into the car and got back in himself," Crowley reported told police, according to WFAA. "He hit me with his open hand on my left ear for jumping out of the car. I realized immediately that I could not hear out of that ear, and I still cannot today, two days later."The Houston Chronicle, citing the police report, said Crowley told police Manziel struck her "several times" and appeared to be "on some kind of drugs." The Chronicle's story said the alleged assault happened in Manziel's hotel room in Dallas, and that Crowley claimed Manziel struck her more times as he drove her home, though the police report says Crowley "again was somewhat vague on the details of the assault." WFAA said that Manziel threatened Crowley more at her apartment, Crowley pulled out a knife and Manziel fled. Crowley "began to become irritated with the officer's questioning" when asked about a further assault at her apartment. The police report said Crowley "became increasingly uncooperative" and refused to fill out a statement or make a report, and wouldn't let officers to photograph her or her injuries.WFAA added that Crowley told authorities she "is afraid for her safety and has drafted an order of protection to be presented to a Tarrant County district court judge." TMZ published audio of a 911 call from Crowley's neighbor, who said Crowley told her Manziel "beat her up." The neighbor says on the 911 call that she heard Crowley screaming. The neighbor on the 911 call said Crowley didn't want her to call 911.
