The Sanford City Commission refused to accept the resignation of its embattled police chief Monday, saying the law enforcement leader has a spotless record and deserves more time for the city to determine whether he bungled the Trayvon Martin probe.

A month after handing down a no-confidence vote against Chief Bill Lee, the same commission voted 3-2 to keep him on. Lee took a paid leave of absence last month after coming under fire for his handling of the investigation into Trayvon’s killing.
