A Central Florida man was sentenced to life in prison for murdering his girlfriend's 13-year-old daughter, who went missing and was found dead days later.

The Florida Department of Corrections has released a new mugshot of Stephan Sterns after he was booked into the Central Florida Reception Center. Sterns will spend the rest of his life in a state prison.

Prosecutors say Sterns killed his girlfriend’s daughter, 13-year-old Madeline Soto, in February 2024. They allege he raped her repeatedly before her death. On Monday, Sterns pleaded guilty to pleaded guilty to the sex crimes and no contest to murder. The plea came one day before he was going to face a jury in the sex crimes trial.
