Following claims from a law enforcement official that the NFL did receive video of ex-Baltimore Raven running back Ray Rice assaulting his wife, the league has appointed a former FBI director to conduct an investigation.

Robert S. Mueller III will be carrying out the investigation into how the league handled evidence in Rice’s domestic violence case.

Roger Goodell, the NFL Commissioner under fire for handing down Rice’s lenient two-game suspension while he may or may not have known about the disturbing elevator video, announced Mueller’s appointment on Wednesday. Goodell maintains that law enforcement authorities and casino officials declined to provide the video.

From the Baltimore Sun:

The NFL announced that Mueller will have full access to NFL records and personnel.

His investigation will be overseen by New York Giants owner John Mara and Pittsburgh Steelers owner Art Rooney.  Mueller was FBI director for a dozen years from 2001 to 2013. He’s currently a partner in the law firm of WilmerHale and is based in Washington, D.C.

A full report will be made public when the investigation is complete.

Meanwhile, a source close to Rice tells TMZ Sports that the altercation between he and then-fiancée Janay Palmer (now Rice) was fueled by alcohol.

Rice told the Baltimore Ravens he and Janay Palmer had been drinking HEAVILY before the altercation. Rice is telling friends he becomes a different person when he boozes it up … so he’s changed his life.

But he hasn’t changed that much, because we’re told he still drinks wine … just not hard liquor.

Our sources say Ray and his wife have gotten deep into religion since the February incident — they were both baptized in March when they decided to become Born again Christians.

We’re also told they’ve also done religious mentoring with other couples … including NFL players and their wives.

Both Rice and Janay released statements on Tuesday suggesting they are working on their marriage.
