Five arrests were made in relation to the death of California high school football player Griffen Kramer, son of former NFL quarterback Erik Kramer.

Three adults and two juveniles were arrested after executed search warrants on six locations on Thursday, according to reports.

Nineteen year old David Nernberg was arrested on suspicion of involuntary manslaughter; however, he has been released on bail. The four others, on the other hand, were apprehended for misdemeanor charges.

The police said that they also arrested two other adults and two other juveniles for related misdemeanors.

The 18-year-old Kramer was found dead at Nernberg’s house last month. While the initial analysis suggests that his death was caused by drug abuse, the final cause is pending a toxicology report.
