PRAGUE, Czech Republic—A former Franklin man and front man of the Richmond-based heavy metal band Lamb of God on Monday admitted to pushing a fan off a stage, who died two weeks later of head injuries.

Testifying in Prague during the first day of his trial on involuntary manslaughter charges, Randy Blythe, 41, said he saw the 19-year-old man stand up in the crowd after he pushed him onto a concrete floor during the concert in May 2010.

Reports indicate the man was not drunk or under the influence of drugs when he repeatedly attempted to get on the stage.

Blythe, who lived on Barrett Street and attended S.P. Morton Elementary School, Hayden Middle School and Franklin High School for two years before moving to Chesapeake, faces up to 10 years in prison.

Czech police detained Blythe on his arrival at Prague airport in June 2012. Five weeks later he was released.

Lamb of God has a 2013 Grammy nomination for the best hard rock/metal performance with their song “Ghost Walking.”
