Cops have arrested a “jealous” man over the murder of this beautiful OnlyFans model, whose lifeless body was found in a guesthouse with at least 14 stab wounds.

Melani Juarez, 21, was found dead in the guesthouse she had been living in in the Argentine city of Rosario on Monday, 17th January.

Her friends had started to worry after she stopped answering her phone on Sunday, and one of them went to the guesthouse, only to find the door to her room locked.

As she left the guesthouse, she passed a man, who reportedly told her: “Are you looking for Melani? She’s gone. I saw her at 11am getting into a pickup with a man.”

However, it was a lie, and cops have now arrested the man, identified as 27-year-old Mathias Ezequiel Dominguez, who had been residing in the same guesthouse.

When he and Melani’s friend crossed paths, the young woman had already been dead inside her room for over 24 hours.

Her body was eventually found by her sister after she went to the guesthouse with two police officers. They had to enter the locked room via a side window.

The lights were off and the TV was on full volume when they gained entry. The victim’s lifeless body was found on the floor with multiple stab wounds.

Her mobile phone was missing and has not been recovered to this day, and the post-mortem found that she had defensive injuries in addition to the stab wounds.

Fifteen witness statements were taken by investigators, and all reportedly mentioned Dominguez, who was a former casual worker for a delivery company.

An unnamed resident of the guesthouse was quoted in local media as saying: “Mathias checked into the guesthouse on 17th December 2021.

“The relationship between him and Melani wasn’t good. She was friends with a guy named Fabian who lives in the next building, and Mathias, despite having only known her for a few days, was jealous and hounded her.”

The investigators believe the crime took place in the early hours of Sunday, with a resident spotting Dominguez washing his hands in the bathroom shortly afterwards.

Dominguez unexpectedly left the guesthouse with his belongings, despite having paid for the whole month, on the Monday.

He was arrested near Rosario after first having sought refuge at his mother’s house in the town of Alcorta. He is accused of aggravated murder.

The crime is still under investigation, but investigators preliminarily believe it may have been a sexual assault gone wrong.

The suspect exercised his right to remain silent at his hearing on Monday, 31st January.

According to local media, Melani was a dancer and earned a living through charging for erotic content she posted to OnlyFans.
