OKLAHOMA CITY - A father told News 9 he shot his son as police carried him into custody Wednesday night.

Police say the man they took into custody is D.E. Abbott.

Police say Abbott drove to a gas station, telling workers he shot his son, Perry Abbott, at their home.

Workers at the Flying J near I-35 and N.E.122nd heard a man laying on the horn from the parking lot, so they came out to see what he needed.

That's when the manager tells News 9, D.E. Abbott told her and the supervisor that he shot his son and why.

"Very sad situation. Kind of scary," said the store manager, who did not want to be identified for this story.

The workers called 911 and this woman talked to the 72-year-old father until they arrived.

"I turned to the gentlemen and said ‘Why did you shoot your son?' He said to me, ‘Because he's held me captive in my own home since last September.'"

Abbott continued to talk from his RV while another worker was on the phone with police dispatch.

"I said, ‘Do you have the gun now?' He said, ‘Ya' and I said ‘Really?' I started taking steps backward and I said, "Well, I don't want to get shot,' and he said ‘I'm not going to shoot you.'"

The store manager can't explain why, but says she wasn't scared. Then she said in the middle of their talk Abbott asked for her help.

"The gentlemen said, ‘Please, get an ambulance,' and yelling the address and said "he's either bleeding to death or already dead.'"

The store manager said she's not sure what was happening inside the home where the father and son lived, but hopes Abbott gets help.

"The one thing I noticed is he's not well," she said.

Police had to carry Abbott away from the store. He told workers and officers that he was "crippled."

The manager we spoke with didn't see how or when he went inside, but when she asked him how he was able to get inside the RV to drive he said he crawled.
