Officer Lopez is a police officer of the Starling City Police Department.
After Isaac Stanzler left the abandoned nightclub that he led Ted Grant into, the police then arrived. Lopez arrested Ted on multiple counts of homicide. Ted denied this, stating that he nothing to do with it, however she revealed that they had found a body in his locker.
When Captain Lance arrived at the police department, Lopez told him that someone had hacked into the emergency broadcast system, and they'd taken over all the networks. She then listened to Oliver's announcement (in the persona of Green Arrow) that he was the successor of the late Arrow, and aspired to be the symbol of hope that his predecessor never was.
