A 19-year-old man from Washington State has been arrested for allegedly raping a female acquaintance as she was dying from an opioid overdose, bragging about what happened to friends and then stuffing her body into a bin to go to work.

Brian Roberto Varela, of Lynwood, was taken into custody on Tuesday on suspicion of manslaughter, homicide by controlled substance and second-degree rape in the death of 18-year-old Alyssa Mae Noceda.

According to a graphic police report filed in court and obtained by DailyMail,com, on Saturday night, Noceda, a student at Mariner High School, had gone to a party in a mobile home park in Lynwood, where she met Varela.

Noceda, who had recently split from her boyfriend, followed Varela to his bedroom, where she snorted a long line of the prescription painkiller Percocet and passed out after Varela offered her a 'dab' of liquid THC, as the suspect and other witnesses told police.

Instead of calling for help, or taking Noceda to the hospital, Varela allegedly raped her. He later told his friends that he did not know 'if she was alive when he ejaculated into her,' according to the report, also seen by KIRO7.

Later that night, some of Varela's friends received a group text message that included photos of a unconscious woman with swollen blue lips dressed in nothing but a pair of white Calvin Klein underwear.

'LOL I think she od'd, still breathing,' Varela texted, according to the report.

The suspect then added, using a crude term for sexual intercourse: 'I'm smashing her to pass the time.'

He later reportedly boasted to a friend that Noceda 'died having sex with me.'

Varela briefly considered driving Noceda to the emergency room, but told a friend he was 'too tired to do so' and went to bed instead, leaving the teenage girl for dead, the report stated.

When he woke up the next morning, he discovered that Noceda has died. He allegedly showed her body to his roommate, who later recalled to the police that the victim appeared stiff and had foam around her mouth.

Instead of contacting police, Varela locked his bedroom, with the woman's lifeless body still inside, and went to work a double shift at a Dairy Queen.

As his co-workers told police, Varela allegedly bragged at work about having sex with Noceda and described in graphic detail how he had broken her legs to load her body into a plastic bin, which he was planning to fill with onions and bury.

One of Varela's colleagues contacted the authorities after seeing a Facebook post written by Noceda's mother reporting that her daughter was missing.

Police responded to Varela's mobile home on Tuesday morning and found Noceda's lifeless body stashed inside a black bin.

When questioned by police, the 19-year-old suspect admitted to having sex with Noceda but insisted that even though she was 'out of it,' the encounter was consensual.

After the teen died of a suspected drug overdose, Varela said he attempted to wash his DNA from her body, stuffed it inside a crate and researched how to get rid of a body. He claimed he was too scared to call the authorities.

After reading Noceda's mother post on Facebook, Varela said he used Alyssa's thumb to unlock her iPhone and update her Snapchat to make it appear as if she had run away from home, which she had done before. He then dumped the device at a construction site.

Police have since recovered the dead woman's phone and are reviewing its contents.

Varela made his initial court appearance on Wednesday and was reportedly seen smirking, reported The Daily Herald.

A prosecutor argued that Varela showed 'a callous and shocking disregard for human life,' and a judge ordered the man held in jail on $500,000 bail.

Noceda's aunt has launched a GoFundMe campaign to help pay for her funeral. As of Friday afternoon, just short of $5,000 has been raised.
