Pregnant porn star Amy Days has been found dead with stab wounds in a Saint Petersburg hotel after allegedly being killed by her ex-husband who treated her like a sex slave during their relationship.

He was found in serious condition with a broken back and fractured limbs, as well as a stab wound, seven floors down but survived and has since allegedly confessed to the authorities that he killed her and wrote a fake suicide note to cover it up.

The 38-year-old woman, real name Ekaterina Andreeva, was found dead at the hotel and her ex-husband was found on the pavement outside, seven floors down.

The ex-husband, named only as Dmitry G., 30, was taken to hospital with serious injuries, according to local media, who said he suffered several fractures to his vertebrae and limbs, as well as a stab wound.

The lifeless body of Amy Days, who was five months pregnant and a mother of one, was reportedly discovered in the hotel room on 18th May.

The police are said to have found a suicide note near the actress’ body in which she said goodbye to her family and friends and asked for forgiveness, but her ex-husband has allegedly admitted that he wrote this in a bid to cover up the killing.

She had reportedly fled the abusive relationship and managed to stay away from him for months.

In the meantime, she met somebody else and became engaged.

Local media quoted an unnamed friend of Amy as saying that she had divorced her husband because of his abuse and had confirmed she had found a new fiance who she had been dating for one and a half years.

Amy was pregnant with a baby girl by her new fiance, and one of her last acts was to contact a registry office to set a date for her wedding.

Her last message to her fiance before her death reportedly read: “I got wedding catalogues, I need to prepare for the celebration, otherwise in July there is trouble with booking.

“I love you madly and I want to become officially a wife as soon as possible, and not in words! I hope you haven’t changed your mind.

“I feel so sad without you. I worry about you. Thanks for helping me, bunny. I wouldn’t have coped without you, it’s hard and bad for me.”

Dmitry G. had reportedly used her Telegram account to message her new fiance, who was not named, saying: “Don’t write to me anymore, I’m happy with someone else. We’re already like a family.”

Russian law enforcement reportedly quote the suspect as saying: “I waited until she bled to death and wrote a suicide note, ostensibly on her behalf.”

Amy reportedly suffered nine neck injuries and five stab wounds to her shoulder.

The murder investigation is ongoing.
