Linda O'Brien said , and a Black Hawk helicopter was being utilized . `` We are continuing to pursue all leads until we find '' Labeet , said Miami-Dade Mayor Carlos Alvarez . Watch a report on the manhunt » . A $ 22,000 reward was offered Thursday night for information leading to Labeet 's arrest , O'Brien said . The shootings happened about 11 a.m. as the officers were on a burglary detail at a housing complex in Cutler Bay , Florida , Alvarez said . They saw a vehicle driving erratically , he said , stopped it and confronted the man police believe is Labeet . The man got out of the car and opened fire with an assault rifle , Alvarez said . `` Without any remorse , Labeet left the officers there to die and fled the scene . '' The rifle used in the shooting was found at a nearby canal , but authorities say the man may have another weapon . Alvarez said the officer who died was 37 years old and survived by a wife and two young children . He had been with the department since 2003 . A second officer , 31-year-old Jody Wright , remained hospitalized Thursday night . Her father , Dennis Dalley , told reporters she had undergone surgery as doctors tried to save her leg . He said he remains hopeful they will do so , but that will require many more surgeries . Dalley said Wright has been an officer for about a year and a half . The two other officers , ages 36 and 34 , had been released from the hospital Thursday night , Alvarez told reporters . `` By the grace of God , we do n't have four officers dead , because he certainly tried his best , '' he said . `` There were multiple , and I mean multiple , rounds fired at the police officers ... . That man did n't hesitate to shoot . '' There was initial confusion regarding the identity of the suspect , Alvarez said , because Labeet 's girlfriend , who was apprehended at the scene of the shootings , gave authorities the wrong name . `` She purposely misled and delayed our investigation , '' he said . Labeet , 25 , had stolen the identity of another man , Kevin Wehner , 30 , Alvarez said , and had been using Wehner 's name and identification . That was the name initially given to police . After Wehner 's name and picture were released to the media , the real Wehner contacted the Jacksonville , Florida , Sheriff 's Office near his home . Jacksonville authorities said Wehner had come to the sheriff 's office and been interviewed , and police were confident he was not involved and was a victim of identity theft . The girlfriend will likely face charges for providing false information , Alvarez said . Labeet has an outstanding warrant for aggravated assault from September 2002 , police said Thursday night . Meanwhile , a law enforcement source said officers are working three locations in adjacent Broward County . The suspect 's mother , brother , a woman believed to be the brother 's girlfriend and her two children were being questioned at the Broward County Sheriff 's Office , the source said . Officers also were at a grocery store warehouse where the suspect 's mother works in Deerfield Beach , Florida , and at the mother 's home in Margate , the source said . A car believed connected to Labeet was found at a Target store in Fort Lauderdale , Florida , a few hours after the shooting , police said . It was occupied by a man , woman and two children , who were being interviewed , O'Brien said . The car , a 2007 black Pontiac Vibe , was rented to Labeet 's brother , Shane Labeet , according to Kevin Meyer , a spokesman for the car rental company . Parts of the complex where the shooting occurred were evacuated . Alvarez said Thursday night he had no information on when residents might be allowed back in their homes . E-mail to a friend .
