Rapper Master P is offering a reward to anyone who can provide fresh information to help police officers track down the killer of a Kentucky man.

Charles Fambrough was fatally shot on Christmas Eve, 2012 (24Dec12) in Louisville, Kentucky and the investigation into the 22 year old's death is about to become a cold case as police officers have been unable to uncover any new leads.

The hip-hop star, real name Percy Miller, has now made a public plea and offered a reward to encourage locals to come forward with information which could help bring those responsible to justice.

He tells local Tv station Whas11, "Somebody come forward (or) whoever got anything to do with this or you know somebody - somebody sitting around bragging at home thinking it's a joke, it's not a joke... you took somebody out from somebody's loved one, that really missed that person... they should be here with their family."

On 26 December (14), Miller teamed up with Fambrough's former fiance Megan Brown to hand out bicycles to children who had lost a parent to violence.
