Prosecutors asked Eastern Uusimaa District court to jail a man accused of stabbing to death a 26-year-old transgender woman in the home they shared.
The hearing started on Friday, with prosecutors stating that the accused stabbed the victim to death on 12 June 2020.
The victim died within minutes after receiving three stab wounds. Prosecutors say the attacker intended to kill the victim, and are demanding a prison sentence.
The accused has admitted his guilt.
When first reported, the case was the focus of disquiet from transgender groups as police misgendered the victim when they first announced it.
Trans activists said the police statements and media coverage of the case had been offensive.
Ilta-Sanomat was the first media to report the case, and it said the victim had been a man even though trans organisations had confirmed from multiple sources that the victim had lived as a woman for several years.
The court documents do not take a stand on the victim's gender, but use her legal name. Trans groups said last summer that the victim's legal gender was male because of Finland's poor legal provision for the recognition of transgender identities.
The current government has said it will reform laws around transgender people, which currently demand people are sterilised before their new legal gender can be legally recognised.
