WILLOW PARK – A witness to the shooting in Willow Park Saturday evening that left two women dead told police that the victims were extorting the hospital official accused of killing them.
Christopher Mark Wall, a 33-year-old registered nurse and director of behavioral health quality and administration at John Peter Smith Hospital, was arrested early Sunday morning on a warrant for capital murder of multiple persons.
Ashley Pohorence, 23, died to a gunshot wound of head and neck, and Krista Kay McClellan, 21, died due to a gunshot wound to the head, according to the Tarrant County Medical Examiner.
A third woman, 23 years old, witnessed the shooting and escaped in a vehicle, according to a probable cause affidavit filed by Willow Park Police CID Sgt. Jaclin Ramirez.
The woman told police that she, Pohorence and McClellan came from Arlington to meet with Wall.
The witness reported that she knew Wall from going to Wall's workplace the day prior and giving him a massage with McClellan after Wall contacted them through Backpage, a classifieds service known for its adult section.
The witness 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, according to the probable cause affidavit.
The following day, McClellan and Pohorence contacted Wall again, according to the probable cause affidavit, and the witness assumed the meeting with Wall was to get more money from him.
Wall provided the address of the bank, according to the witness.
"[The witness] stated she stayed in the vehicle as Pohorence and McClellan got in a maroon/red vehicle with Wall," Ramirez wrote. "[The witness] stated after a few minutes, Pohorence and McClellan began to hurriedly exit the vehicle, and Wall got out and began shooting them with a firearm."
The witness told police that she fled in her vehicle to the gas station across the street and saw Wall flee south on FM Road 5 in his vehicle.
