MORICHES - Police say alcohol may have played a role in an accident that injured two teenage girls in Moriches last night. According to detectives, the accident happened at around 7:15 p.m. when 17-year-old Kelly Semon, of Patchogue, was heading home with her 17-year-old friend, Rebecca Henderson, from Medford.

They say neither girl was wearing a seat belt at the time of the crash.Semon was rushed to Brookhaven Memorial Hospital, where she is now listed in stable condition. Henderson was taken to Stony Brook University Medical Center. Her condition is unknown.
