PITTSBURGH — A man charged with robbing and killing two sisters turned himself in to Pittsburgh police Wednesday after professing his innocence on Facebook and claiming he had been framed.

Allen Darell Wade, 43, was wanted on charges including criminal homicide, robbery, theft and a firearms violation in the slayings of Susan Wolfe and Sarah Wolfe, his former neighbors.

The two sisters of state Rep. Mary Wolfe, of Clinton, Iowa, were found dead Feb. 7 after police were called to their residence when they didn’t show up for work. Both women were found in the basement of the home they shared; each was shot once in the head, police said.

Sarah Wolfe, 38, was a psychiatrist for the University of Pittsburgh Medical Center’s Western Psychiatric Institute and Clinic. Susan Wolfe, 44, was a teacher’s aide at Hillel Academy in the city’s Squirrel Hill neighborhood.

Wade was questioned by police late last month but released. He denied wrongdoing at the time.

Lt. Kevin Kraus said Wade had since vacated the home next door to the Wolfes’ residence and police were searching for him Wednesday before he turned himself in. They provided no other details on his surrender, though Kraus said police were alerted to Wade’s plans by monitoring his Facebook page.

On it, Wade professed his innocence, writing, “I would like for the world to know I am 100 percent innocent I would never ever in any way Hurt a person so brutally it is not in my nature I have always respected women and will always continue to do so I am being framed to take the fall for this case and hopefully justice will prevail !”
