Exterminator charged with strangling Philly doctor Associated Press Copyright 2013 Associated Press. All rights reserved. This material may not be published, broadcast, rewritten or redistributed. Updated 10:23 am, Thursday, January 24, 2013 PHILADELPHIA (AP) — A suburban exterminator has been charged with strangling a young Philadelphia doctor found bound and burned in her downtown row home, police announced Thursday. Smith "struck her while she was in the basement, knocked her down, strangled her to death and ultimately set her body on fire" in an apparent attempt to hide evidence, Clark said. There were no signs of sexual assault and nothing was stolen from the home of the victim, whose body was bound with rope at her wrists and ankles and wrapped around her neck, police said. Investigators said Smith, who lived with his longtime girlfriend and her young child, and Ketunuti, a second-year infectious-diseases fellow and researcher at the renowned Children's Hospital of Philadelphia, had never met before.
