A wild crime outside our nation's capital all starts with a violent home invasion, and ends with a suspect being arrested wearing nothing but an adult diaper.

The only more shocking than what happened here inside one of Washington's wealthiest suburbs was who police say did it.

A prominent attorney and his wife are savagely attacked in a grisly home invasion.

When cops later pull over the getaway car, what they find is unbelievable.

Leo Fisher and his wife Susan Duncan, both 61, were living a great life. Susan was recently retired from a career in government. Leo was a respected attorney and managing partner at a law firm.

And their upscale neighborhood of McLean, Virginia was comfortable, quiet and safe.

Until one evening, when their bliss turned to bloodshed.

But this was no normal home invasion -- the suspect has been on the phone talking to a partner the whole time.
