(Scroll down for video) A man was arrested on charges of murder after a female doctor was found bound and dead along with burns inside her Pennsylvania home.
The suspect, who works as an exterminator, has been accused of strangling the Philadelphia physician.
Jason Smith, 36, was arrested Wednesday night, at his home in Levittown, about 25 miles northeast of the Philadelphia, police officer James Clark said.
Smith was charged with murder, arson, abuse of a corpse and risking a catastrophe in the murder of Dr. Melissa Ketunuti, 35, on Monday afternoon.
He had no criminal record other than minor traffic violations, Clark said.
"She needed an exterminator, she called a service, which sent Smith," Clark said. "They got into some kind of argument. It went wrong, very wrong," Clark said.
Smith had an appointment at Ketunuti’s home the day she was killed. He gave a statement that he attacked her and killed her after an argument, police said.
Smith hit her while she was in the basement, knocked her down, strangled her to death and
eventually set her body on fire in an apparent attempt to hide the evidence, Clark said.
There were no signs of sexual assault and nothing was stolen from the house of the victim, whose body was tied with a rope at the wrists and ankles and rope was wrapped around her neck, police said.
Police too Smith into custody at 9:00 p.m. Wednesday, at the home he shared with his girlfriend of six years and his daughter. The girlfriend’s parents also live in the house. Smith has a son who does not live with him.
