VP of security Milt Ahlerich retiring

Milt Ahlerich, whose last major investigative assignment may have sealed Brett Favre's retirement, has tendered his own retirement after serving as the NFL's vice president of security since 1996, league officials confirmed Friday.

Ahlerich, who served in the FBI for 25 years before being hired by the league, spearheaded all of the major security matters that consistently confronted the NFL, including the Patriots' infamous Spygate scandal in 2007 and Favre's alleged dalliances with former Jets game hostess Jenn Sterger, which consumed his time during the second half of the 2010 season.

Favre ultimately was fined $50,000 by NFL commissioner Roger Goodell for his lack of cooperation in the Sterger case.

Ahlerich had targeted 2011 as a possible retirement year. There is no one yet in place to succeed Ahlerich, but the NFL will conduct a thorough search, including candidates from his own security staff who served under him. He oversaw a staff of 11 security professionals and 70 security consultants, with an annual budget of more than $12 million.

Ahlerich had a distinguished career with the FBI, advancing as director of the FBI's forensic laboratory. He also is a member of the U.S. State Department's Overseas Advisory Council.

Ahlerich graduated from Kansas State University in 1968 with a degree in psychology and attended C.W. Post University on Long Island for advanced studies in criminal justice.
