"Though I must take comfort in knowing that he is at peace with our Lord, I also know the agony our family is going through, knowing someone hit him head on and just left him there to die.

"My sweet cousin, I love you so much. This world was a better place with you and your kind, creative heart in it. We will never forget you and will carry you with us forever.

"My family and I are pleading for any information which could help support the investigation into the tragic death of this incredible man.

"I ask that whoever did this, has the dignity and strength to come forward. Our God is a loving and forgiving God, but I pray for justice for John Boy and closure for my family. #JusticeForJohnBoy."

Scherzinger, who was raised in Kentucky, also shared the same message on Twitter.

The former Pussycat Doll is currently in the UK filming for The X Factor: Celebrity live shows, which began last Saturday.
