ORLANDO -- The family of a man killed in his own apartment is pleading for the shooter to turn themselves in.

Orlando police are investigating the possible murder of Tony Johnson, Jr., 25.

Police said Johnson was found dead Wednesday at the Waterstone Apartments off of Long Road.

Johnson’s sister said her brother lived with his girlfriend and their three young children, ages 1 through 4.

His family believes Johnson was robbed, and said his pockets were turned inside out.

"I hope you're listening because if you wanted to rob him, you didn't have to kill him, and if you're going kill people, don't rob them, and if you're going to rob them, don't kill them," said Mary Sapp, Johnson’s grandmother.

"His girlfriend called my grandma, and my grandma called me to come. I was picking my baby up from school. And when I got here, I ran upstairs, and he was already laying there. He was already dead," said Terri Johnson, his sister.

Orlando police have no suspects at this time.
