(Speaking in the voice of America's Most Wanted's John Walsh): We've seen a lot of scumbags in our day, but this guy takes the cake. Frederick McLean is an alleged sexual predator of the lowest kind.

Authorities allege McLean met many of the child victims through his work as a local Jehovah's Witnesses leader in San Diego. At one point Riverside County authorities were also called to take care of this alleged monster. The 58-year-old is facing multiple counts of sexual assault on a child, with one victim claiming that McLean assaulted her more than 100 times starting when she was 5-years-old.

Federal authorities want McLean so bad they've put him the U.S. Marshals' national, 15 Most Wanted list. This poor excuse for a human being needs to be caught, because law enforcement sources believe this kind of suspect could strike again. “McLean possesses many of the factors correlated with reoffense,” stated Michael Bourke, chief psychologist for the U.S. Marshals Sex Offender Investigations Branch. ” … Stress, including the stress that comes with being a fugitive, increases the risk for abusive acting out.”

And this suspect is wily, too. Authorities think he prepared to spend his days on the run six months before a warrant was issued for his arrest in 2005. Family members stated that McLean admitted to his alleged crimes and that he proceeded to liquidate his assets, including his beloved pickup truck.

If you've seen this scumbag and can help bring him to justice, there could be a $25,000 reward in it for you. Call the U.S. Marshals' 24-hour phone line at 1-800-336-0102. And prepare to step back. He's believed to be armed and dangerous and possibly even suicidal.

Now let's go to the America's Most Wanted stats: McLean is white, weighs in at 170 pounds, measures 5 feet, 11 inches, and has hazel eyes and graying brown. He is an auto mechanic and once restored race cars from the 1960s and '70s. McLean is also an experienced outdoorsman who might be spotted at camping areas.

McLean, if you're reading now, turn yourself in. And to our viewers, If you've seen this low-laying, alleged piece of dirt, you know what to do.
