A grieving aunt yesterday showered praise on her 10-year-old nephew who witnessed his dad’s slaying and then bravely picked out the suspects in a police lineup.

“He’s my little man. All he wanted to do was make sure that they were caught,” said Sylvia Caballero, of The Bronx.

William Cain, 26, and Efrain Soler, 18, are charged with murder, manslaughter and weapons possession in the killing of Raul Rolon.
