Police said Officer Huesca was shot multiple times in what they believe was a carjacking as he returned to his Gage Park home early Sunday morning from a shift, still in uniform.
Investigators have now been searching for a man seen in surveillance video who they believe is a suspect in Officer Huesca's murder, for days.
"It's not fair that he's not here and whoever did this is still running free living their lives... and our lives... our lives are... on pause and the pain is unbearable," O'Brien said.
If there is any way to comfort their agony, the Huesca family says, the people of Chicago need to find their brother's killer
