Wohlschlaeger's third wife, Gloria Potts, who was tracked down on Facebook by Sharon Yeomans, said she too was traumatized by her former husband.
"I felt like I was being poisoned," Potts told “20/20” in September.
Potts also recalled one night from years earlier when she was asleep “and he hit me in the back of the head with a mallet."
"Then his hand came ... and covered my nose and mouth," she added.
Potts said she went to the hospital, but told them she had fallen in the tub. She and Wohlschlaeger did not divorce until about 10 years later, and she didn't tell anyone this version of the story until the time of their divorce when she also got a restraining order, she said.
The murder charge isn't the first time Wohlschlaeger has been charged with a crime. Nearly 20 years ago, police found Wohlschlaeger standing across the street from his chiropractic office, watching it burn. He claimed he had been trapped inside and that someone was trying to kill him. Wohlschlaeger was later convicted of arson. He received 15 years probation but no prison time.
