Police are searching for two suspects, who -- they say -- set off the chain of events that landed a female Nassau County police officer in the hospital, after her pursuit of them on the Southern State Parkway ended in a serious crash.

The unidentified officer was listed Monday evening in critical-but-stable condition; police would only describe her as a wife and a mother, who joined the NCPD in 1992.

Investigators say a call came in around noon about two individuals acting suspiciously, a witness telling authorities they were in the midst of switching license plates from Pennsylvania tags to Florida tags on what looked like a metallic grey Honda Accord.

According to police, when the officer arrived, the pair took off along the Southern State Parkway. A high-speed pursuit ensued for several miles. And as the officer began closing in on them, police say the driver slammed on the brakes. That's when the female officer veered off, hitting a guardrail, allowing a second car to slam into her cruiser, before it came to rest underneath the Route 110 overpass. The second car sustained minor damage; its passengers were not hurt. The suspects got away.

The investigation closed down the parkway for several hours.

Already, detectives have a backlog of 10 to 14 robberies on the books in North Massapequa, which they're still trying to solve. It appears this all may've started out as a robbery-in-progress, so detectives can add this on one to the list, also. Nassau County police have released surveillance snapshots of the vehicle, showing the suspects inside the four-door Honda.

If you have any information that can help this and other crimes, please call the Nassau County Police Crimestoppers hotline at 1-800-244-TIPS. All calls will be kept confidential.
