Former Cowboys star WR Michael Irvin won't face sex assault charges

Former Cowboys WR Michael Irvin won't face sexual battery charges in Fort Lauderdale due to a lack of evidence, according to the Broward State Attorney.

NFL Hall of Fame wide receiver and former Dallas Cowboys star Michael Irvin won't face sexual battery charges in Fort Lauderdale.

The Broward State Attorney's Office announced it did not have enough evidence to "establish that a crime was committed," wrote Asst. State Attorney Christine Adler in a report obtained by our news partners at the Sun-Sentinel. "Without additional evidence to corroborate the victim's account of what occurred, we would not be able to prove beyond a reasonable doubt that a sexual battery occurred."

The investigation began in March when a woman claimed Irvin, who played his college ball at the University of Miami, forced himself on her for sex after a night of drinking. The woman believed something was put in her drinks, according to her account to investigators.

According to the State Attorney's Office, Irvin denied any sexual activity occurred. Investigators also said a toxicology report showed the presence of Amphetamine, cocaine and alcohol in the woman's blood. She said she took Xanax and Ecstasy a few days before she claimed Irvin assaulted her. She also said she took Adderall for ADD. But she denied taking any drugs with the defendant.

According to the report, a toxicologist in the medical examiner's office found it unlikely for those drugs to be present in her blood and urine "for over 48 hours after she claims to have taken them." The drugs "would have to have been consumed at a more recent time period," according to the State Attorney's Office conversation with the toxicologist.

Irvin is set to hold a news conference with his attorney at 2 p.m. in Fort Lauderdale. CBS12 will stream it live. (Mobile users click here to watch)
