During sentencing at York County Superior Court on Thursday, Assistant District Attorney Kyle Myska called Hall ” dangerous” and said he had a history of violence.

Hall had targeted the victim because she worked as a guardian ad litem in a custody issue involving his children several years ago.

Myska told Justice Delahanty that Hall’s desire to get his children back led to the idea of kidnapping those involved in the custody issue. He said Hall had planned tie up those individuals in the woods and hold them for ransom.

“He contacted the victim and then laid in wait for her…..he was there and waiting,” said Myska. “Before she got out of her car, he pounced on her and tased her over and over again on her legs. She was able to fight him off.”

Hall had made a stun gun by attaching a taser to a cane. It was initially described as a cattle prod.

Hall drove away but was later arrested after an investigation by the York County Sheriff’s Office.

The incident took place outside a home on Irving Road in Arundel.

“This was not spur of the moment; it was a coldly calculated plan he had been thinking abut for years,” Myska told the justice.

Myska said Hall has a lengthy criminal record.

Hall’s father, John P. Hall, asked the judge to show mercy for his son.

“Being a parent and doing what is right was taught to my son,” the elder Hall said.

He said his son had he helped in the aftermath of Hurricane Katrina in New Orleans, was paid well for his work, and would hand out $50 bills to kids there.

“He was generous,” said the elder Hall, who also said his son has “has a way of expressing himself authoritatively.”

“I am asking you to have mercy on my son,” said John Hall. “I told him not to seek revenge. I told him that belongs to the Lord. I’m asking you to have mercy on him.”

York County District Attorney Kathryn Slattery said she was pleased with the sentence.

“The sentence imposed by Justice Delahanty reflects the seriousness of Christopher Hall’s behavior and the continued threat he poses to public,” said Slattery in a statement. “The victim he has hurt and threatened can now have some measure of peace as she moves forward with her life. I applaud her courage.”
