Psychologist dies after 'asking roommate to strangle her during sex'

A psychologist died after asking her roommate to slap her and strangle her with a cable during a rough sex session in Mexico.

Juan Ruiz Torres, 32, was arrested after pretty Tania Trinidad Paredes, 23, was at his house in the Tlalpan district of the capital Mexico City.

Torres, a journalist, denied raping her and told detectives she died by accident while they were having sex.He said he had been drinking with the victim and another roommate, Jose Luis Arzate Martinez, when she suggested a threesome.

Torres told police that when Arzate Martinez refused and went to bed, Paredes suggested a rough sex session.He told detectives: 'During the act, she asked me to squeeze her neck and slap her because she liked violent sex.

Torres said he throttled her with a cable but must have overdone it because she suddenly collapsed.

A post mortem examination found the cause of death was asphyxiation and her neck bones had been broken.

Some local media claimed Torres initially denied having anything to do with her death but later came up with the rough sex confession after being interrogated.

The Zocalo news website said they were analyzing cell phones and social networks in a bid to check what sort of relationship Torres had with Paredes prior to the incident last month.

The investigation is still ongoing and Torres has not been charged.
