Scene outside is most likely perp beating feet like no tomorrow with her on the radio with a description and location and probably waiting for backup - then its the typical urban chase. Not likely they got him. For her to chase him herself would be pretty dangerous and likely he'd outrun her anyway. She can't shoot him to stop him from running and if he was smart enough to stuff the gun and walk away calmly he was probably smart enough never to present it to any officers he did see.
