According to reports Alisa Massaro's longterm boyfriend claimed she had become 'obsessed with necrophilia'.

Police investigating the murder in Joilet, Illinois, of Eric Glover and Terence Rankins appeared to discover that their bodies were piled up after they were strangled so that Massaro could lie on them in order to have sex.

Joshua Miner, Masssaro's boyfriend, who is among four people accused of the murders, is reported to have claimed: for years back she wanted to have sex with a dead guy”.

The circumstances surrounding the murders is still unclear, although drugs are believed to have been involved.

Reports suggest that Miner carried out the murders in order to help fulfil Massaro's heinous fantasy.

Police Chief Mike Trafton said: “This is one of the most brutal, upsetting things I’ve ever seen in my 27-years in law enforcement”.

He added: “Not only is this a crime scene, but the disregard for common decency towards human beings.”
