Two Northeast Philadelphians received guilty verdicts this week for separate crimes they committed earlier this year.

Traci Young was found guilty of being part of a mother-daughter prostitution ring. The 39-year-old and her 22-year-old daughter were accused of advertising acts of prostitution on Craigslist. They were arrested in October when they arranged a meeting with an undercover police officer at the home they rented on the 6100-block of Ditman Street. Young pleaded guilty in April.

An Oxford Circle teen was found guilty Friday of third degree murder. Marcquis Walker-Williams was convicted in the July 2007 attack on 69-year-old Kwok Wai-Ho, who suffered severe head injuries when the teen pushed him. Sentencing is scheduled for Oct. 16, and Walker-Williams could received 20-40 years in prison.
