Man Pleads No Contest to Involuntary Manslaughter in Death of Griffen Kramer

An Agoura Hills man pleaded no contest Thursday to involuntary manslaughter in the drug-overdose death of the 18-year-old son of retired NFL player Erik Kramer.

Los Angeles Superior Court Judge Mark Windham immediately sentenced
David Michael Nernberg, 19, to five years of formal probation and 90 days of
community labor, said Deputy District Attorney Keri Modder.

Nernberg was charged in connection with the Oct. 31, 2011, death of Griffen Kramer.

Griffen Kramer–a quarterback at Thousand Oaks High School–died from a heroin overdose, according to the coroner's office.

Nernberg took Griffen Kramer to his home after the teen passed out following a heroin injection at a local park, left him to briefly attend a party, returned home and then woke up the next morning to find him dead, according to the prosecutor.

"We felt that he had a duty of care ... once he took custody of Griffen after he passed out,'' Modder said.

Kramer's father played in the NFL from 1987 to 1999, ending his career
with the San Diego Chargers.
