A Florida man is behind bars and his ex-roommate is dead after a homicide authorities say was motivated by the suspect’s unrequited romantic interests.

According to Fox News, 26-year-old Asgeirr Ulfr allegedly hid in Christina Danielle Scarr’s closet through the night before she was killed earlier this year.

The 20-year-old victim was reportedly found dead in her Apopka home on April 6. Officials indicate she was strangled to death.

New reports from the suspect’s sister suggest Ulfr admitted to his attorney that he killed Scarr, as reported by the Orlando Sentinel.

Danielle Brown claimed that he said “that it was an accident, that he didn’t mean to kill her and he just wanted to scare her and her her because she hurt him so bad.”

According to her account, Ulfr claimed he intended to stage an incident to appear as though he saved her from an invented physical attack.

Authorities say Ulfr waited until Scarr’s boyfriend left to attack her.

Instead of just scaring her, Brown said her brother claimed that Scarr fought back when he attacked her from behind.

“He said she was fighting so hard that he punched her in the face and the stomach and the sides a couple of times to try to stop her from fighting so hard,” she said.

Eventually, investigators say the suspect tied the victim to her bed and choked her until she passed out. After he returned a short time later from throwing out the clothes he had on, he allegedly said he realized she was dead.

He also reportedly shot himself in the foot before calling police with a story about a masked female intruder.

In her communication with detectives, the suspect’s sister went on to say that he said “that he wanted to be (Scarr’s) savior, he wanted to be the one that came in after a quote-unquote intruder and save her.”

The suspect’s attorney said he is preparing a motion to have Brown’s remarks dismissed based on an argument of attorney-client privilege.

Other evidence described in the new court documents includes a Walmart trip two days before the killing during which the suspect allegedly purchased a ski mask, duct tape, zip ties and boots.
