Investigators say they have a possible motive in the murder of two women found in Willow Park Saturday night.
A probable cause affidavit released yesterday reveals that a third woman, Sierra McMahan, claims that she and the two victims, Krista McClellan and Ashley Pohorence, traveled together from Arlington to Willow Park to meet the suspect, Christopher Mark Wall of Weatherford, an administrator at John Peter Smith Hospital. She said the three met Wall through an adult online classified service and gave him a massage the previous day at JPS.
McMahan said she and McClellan extorted approximately $8,000 from Wall Friday by convincing him that they recorded him soliciting them for sex during the massage.
McMahan said they met Wall again Saturday in Willow Park, supposedly to get more money from him. She said she stayed in her vehicle while the two victims got into Wall’s car. She says she fled in her vehicle when Wall shot the two women.
