The heirs of slain concert promoter Eric Johnson are suing Young Jeezy, accusing the rapper of killing their father.

Johnson was shot dead backstage at a Jeezy and Wiz Khalifa concert in Mountain View, California in 2014, and now his family is calling for justice.

The dead promoter's kids claim an eyewitness told Mountain View police officials the shooter looked like Jeezy, and the witness repeated that claim in a deposition - and picked the rap star out of a photo line-up as the killer.

A second witness described the shooter to a police sketch artist, who drew someone that looked "eerily similar to the way Young Jeezy looked", according to TMZ.

Johnson's kids are curious why Jeezy was never charged and they are suing the hip hop star for funeral expenses and other damages as part of a wrongful death suit.
