Prosecutors on Thursday said they are seeking the death penalty for a man charged with murdering three elderly residents at a Kawasaki nursing home in 2014 by throwing them from balconies.

As the trial wrapped up at the Yokohama District Court, the prosecutors said that Hayato Imai, 25, had committed "cruel and despicable" crimes at the facility where he worked and that he is "undoubtedly the perpetrator" since he has made "highly credible confessions to police officers."

Imai, who worked as a care worker at the facility, maintained his innocence, telling the court, "I regret that I made false confessions after succumbing to police pressure."
