Pittsburgh Steelers star Stephon Tuitt is mourning the death of his baby brother, Richard Bartlett III, who was killed in a hit-and-run accident in Georgia.

According to reports, Richard and his girlfriend were pulled over to the right side of McGinnis Ferry Road to try to secure a mattress strapped to the top of her car.

That’s when an oncoming car struck Richard and fled the scene. 

Richard Bartlett III died from his injuries.

Police are asking for the public’s help in finding the suspect’s vehicle, which is described as a dark four-door sedan – possibly a BMW.

Anyone with information is urged to call Officer Hennessee at (470) 774-3358.

Stephon Tuitt posted a photo of himself and his baby brother with the caption:

You are in heaven living streets free. I miss you so so so much bro ???? We love you and see you again one day. 

Thank you for the prayers and calls.
