“Law & Order” actor Jack Merrill said in an article published in PEOPLE Magazine on Thursday that he was kidnapped and raped by serial killer John Wayne Gacy.

Gacy, who died in 1994, was convicted and imprisoned for raping and murdering at least 33 young boys and men in the Chicago area from 1972 to 1978, according to Entertainment.

PEOPLE Merrill said this At the time of the incident, he put the “attack” behind him for years and “only told his closest friends that Gacy had put a loaded gun in his mouth.”

The actress then told in her own words the night she was raped by the clown killer.

Merrill said the incident occurred when he was 19 years old. She said she went swimming at the YMCA and was walking home when Gacy pulled over and asked her if she wanted to ride a bike.

“I thought about driving around the block a few times but he started driving fast and turned into a really bad neighborhood,” Merrill wrote. “He said, ‘Lock your door.’ This is dangerous.” ”

Merrill said Gacy eventually pulled over, “pulled out this brown bottle, poured some liquid on a rag and jammed it in my face.”

“I passed out and when I woke up I was handcuffed,” he wrote.

Merrill wrote that Gacy took him to his home and, once inside, asked him if he trusted him. He wrote that when he told Gacy he had done this, he removed the killer’s handcuffs.

“There was a bar in the middle of the house,” he wrote. “We drank beer and he had a strong container, then he put the handcuffs back on and dragged me down the hall.”

Merrill said Gacy then restrained her, put a gun in her mouth and raped her.

Merrill said Gacy said he would take her home when he was done and dropped her off near where he picked her up. He said Gacy even gave him his phone number.

“I didn’t know at the time that he was a murderer,” she wrote.

“I made a pact that I would get through this,” he added. “I wasn’t going to leave my happiness in that house.”

Merrill wrote that when she saw headlines about Gacy, she called the Chicago Sun-Times and told them the killer had raped her. But when the reporter asked him his name, he refused to share it, he wrote.

“I hung up the phone,” he wrote. “I thought I would come forward if the police needed my help. “They found all these bodies under that house, and years later he was convicted.”
