The 23-year-old suspect was arrested at the crime scene shortly after the act.
He was arrested a few days later and has since been in custody.
In addition to murder, he is suspected of probable cause for both rape and aggravated rape against one and the same woman, and also for aggravated unlawful threats and assault.
In total, it is about a suspected perpetrator and three plaintiffs.
According to chamber prosecutor Stina Sjöqvist, who is leading the preliminary investigation, this is a protracted process during the morning hours, according to what SVT Västernorrland experiences for several hours, as the suspected crimes must have been committed.
The lid on
The origins of what happened have so far been hidden by the police and prosecutors during the investigation.
However, chamber prosecutor Stina Sjöqvist told SVT at an early stage that they had obtained a good picture of what had happened.
During the arrest hearing in Ångermanland District Court on May 13, the 23-year-old contested the arrest - at the same time as he neither wanted to deny nor admit what he is accused of.
The victim from Hälsingland
According to Stina Sjöqvist, all three plaintiffs in the case knew each other well from before, while the suspect is something of an "acquaintance acquaintance" with them.
The 19-year-old murder victim comes from a place in Hälsingland and did his high school studies in Härnösand.
The accused 23-year-old has previously been convicted of a crime on two occasions, including sexual harassment of a minor girl.
He has also appeared in other investigations into crime.
