Tyshawn Lee's father starts selling the T- shirts of his dead kid...

Two weeks ago, 9-year-old Tyshawn Lee was shot and killed by gang members in Chicago. So far police have NOT been able to find his killer.

Yesterday we reported to you that Tyshawn's mother, Kara Lee, took money that was donated to Tyshawn's funeral . . . and bought herself a brand new car -- event though she's now denying those claims.

Well Tyshawn's father decided to make his OWN WEB PAGE. And he's now SELLING T-SHIRTS with Tyshawn's face on it. He is also asking for donations to "help."

What's even worse . . . An alley memorial set up for Tyshawn has been destroyed in a fire. It happened early Sunday in the Auburn Gresham neighborhood on Chi's South Side.

So sad . . . this poor young soul . . . was lured down an alley . . . and gunned down. And now people are taking advantage in his afterlife? This young boy needs to be able to rest in peace.
