CHICAGO (CBS) — After they allegedly murdered two young men, two of the four suspects involved in the savage and bizarre attack decided to have sex on top of the corpses, according to a published report.

The Joliet Patch, citing police documents, reports Joshua Miner told investigators that his girlfriend, Alisa Massaro, once told him that she fantasized about having sex with a dead person.

So, according to the police reports, that’s how Miner got the bizarre idea to engage in sex on top of the two men they had just allegedly killed.

The Patch reports Massaro at first resisted the request. However, they then placed something–perhaps a sheet or a blanket–on top of the bodies and had sex.

Adam Landerman, 19, Massaro, 18, Bethany McKee, 18, and Miner, 24, have been accused of luring Terrance Rankins and Eric Glover, both 22, to Massaro’s home, then robbing and killing both victims. The suspects also allegedly tried to dismember Rankins’ and Glover’s bodies and then continued to party together.

CBS 2’s Marissa Bailey reported at the time that the suspects and victims appeared to be friends.

Joliet Police Chief Michael Trafton said the four suspects were not tested for drugs or alcohol when they were arrested.

Landerman is the son of a Joliet police sergeant.

County records showed Massaro has a restraining order against Miner, who has an extensive criminal record – including a pending child pornography charge.

Trafton said he’s never seen such a disturbing crime scene in his 27 years on the job.

After attempting to dismember the bodies the suspects “continued the party atmosphere,” Trafton said at the time of the arrests in January.

“This is one of the most brutal, heinous and upsetting things I’ve ever seen in my 27 years of law enforcement,” Trafton said at the time. “Not only the crime scene, but the disregard for common decency toward human beings.”

Police were notified about two dead bodies at the house, and officers noticed movement inside the house so they went in, Trafton said.

He said Landerman, Massaro and Miner were playing video games and were “very much surprised” when the police arrived. McKee had left before police arrived but was picked up by authorities in Kankakee, police said.

Morbid: Alisa Massaro, 18, allegedly has a necrophilia fetish and engaged in three-way sex on the corpses of two murdered men

An 18-year-old woman with a necrophilia fetish had three-way sex on the corpses of two men who she and her sexual partners strangled, it was claimed today.

Joshua Miner, 24, piled the bodies of Eric Glover and Terrence Rankins, both 22, together and placed a beige sheet across them so he and his longtime girlfriend, Alisa Massaro, could lie together on top of them at Massaro's home in Joliet, Illinois, according to police reports.

Miner told police he remembered 'years back' that Massaro had told him she 'wanted to have sex with a dead guy,' so he hoped to fulfill part of her fantasy, according to documents.

Adam Landerman, the 19-year-old son of a police sergeant, may have joined Massaro and Miner's sexual romp, as well, the report says.

Patch.com released the revolting new details today in the shocking January 10 murders - allegedly committed by Miner, Landerman, Massaro and 18-year-old Bethany McKee.

Massaro grinned when her boyfriend asked her to have sex and initially declined. Later, though, she admitted that she agreed to it.

McKee told police that she believes Landerman joined the sexual acts, as well.

McKee said Miner was the ringleader who came up with the idea who kill Glover and Rankins. She said Landerman was a 'follower' who only did what Miner told him, according to the report.

After killing the men, Landerman jumped on their backs and 'surfed' on their dead bodies, according to reports.

The corpses elicited a 'zombie noise' - a final gasping sound. The bodies also evacuated their bowels, Miner claimed.

They then hog-tied the victims' hands and feet together with dirty clothes and and an electrical cord.

'This is one of the most brutal, heinous and upsetting things I've ever seen in my 27 years of law enforcement,' Police Chief Mike Trafton said after the January slayings.

'Not only the crime scene, but the disregard for common decency toward human beings.'

Police reports say McKee knew Rankins and invited him and Glover over with promises of sexual favors.

Miner later admitted that they four believed the men had carried 'lot of money' and that they were planning to rob them. They believed Rankins was a drug dealer and carried $100 with him.

'It's demonic,' Rankins' mother, Jamille Kent, said.

'This is evil.'

Trafton, the police chief, said Massaro, Landerman and Miner were 'very much surprised' when police walked in on them Thursday. McKee had left the house but police arrested her later in nearby Kankakee.

Rankin's mother said her son and Glover had been friends for five years.

Family members said they called police on Januaury 10 after they hadn't heard from the two since Wednesday.
