The 17-year-old shot multiple times by a cop while eating outside a McDonald's is on life support after several of his organs were punctured ... TMZ has learned.
Erik Cantu's family, through his attorney Brian Powers, tells TMZ the teen has undergone multiple surgeries to repair major organs that were damaged -- a result of the gunfire.
Erik's being closely monitored as the system keeps his lungs operating. He still remains sedated to hopefully ease the pain and discomfort he'd face if conscious.
Erik is struggling, and the recovery won't be easy for him, but his family thanks everyone for sending prayers ... asking for more of that love during this time of uncertainty.
As we reported, bodycam footage -- released by police last week -- showed San Antonio PD Officer James Brennandshoot multiple times at the unarmed kid. Brennand was at the location for an unrelated call ... but Cantu had apparently evaded Brennand on another call the day before.
Brennand was fired for violating the department's tactics, training and procedures.
