Seth Moretti will spend the next five years in prison for providing the heroin that killed his 15-year-old girlfriend last July.

Waukesha County Circuit Judge Ralph Ramirez on June 16 sentenced Moretti to the prison term and 10 years of extended supervision. The ruling came roughly six weeks after Moretti, 18, pleaded no contest to second-degree reckless homicide in the case. 

Moretti was originally accused of first-degree reckless homicide in December, about five months after his girlfriend Erika Reiner's fatal overdose.

According to a criminal complaint, police on July 8, 2016, found both Moretti and Reiner unresponsive inside Moretti's room at his grandparents' house in the 500 block of Lapham Street.

Reiner was pronounced dead at the scene, but Moretti was rushed to the hospital for treatment, the complaint said. A medical examiner later determined Reiner died of a heroin intoxication.

She reportedly posted about using the drug on her Facebook and Instagram accounts that day, claiming Moretti told her the drug she was taking was cocaine, not heroin, and saying she was upset that he had lied to her. It was possibly the first time she ever tried heroin.

The complaint said Moretti admitted to hospital staff that he gave Reiner the drug and told her it was cocaine. He reportedly said he knew something was wrong with her when he saw how she reacted to the heroin, but told a caretaker he was too "messed up" to help her.

Court records indicate Moretti could be required to provide restitution for funeral costs. A ruling on that matter is pending. 

Conditions of his supervision include absolute sobriety and random drug screenings. Records show he received credit for 183 days of time served.
