Cops: Five arrested in connection with death of high school football player

(CBS) VENTURA, Calif. -- Five people have been arrested in the death of Griffen Kramer, a high school football player who died Oct. 30 of an apparent overdose, police say.

NBC Los Angeles reports that Kramer,18, the son of former NFL quarterback Erik Kramer, died his sleep at a friend's house, possibly of a heroin overdose.

CBS Los Angeles reports that the Los Angeles County Sheriff's Department searched six locations around 7 a.m. today and arrested three adults and two youths in connection with the death.

Lt. John Corina said his department arrested David Nernberg, 19, on suspicion of involuntary manslaughter and four others for unspecified misdemeanor allegations.

"We believe some of these people were involved in some type of narcotic activity that contributed to his death," he told the Ventura County Star.

A reporter knocked on Nernberg's door for a comment, but it was slammed in his face.

Police continue their investigation and are expecting Kramer's toxicology report in a few weeks time.
