At approximately 1600 hours, Company 7 was alerted for a motorcycle 10-50 PI on Route 439 near the Baltimore/Harford County line. Upon arrival, Chief 7 found a male subject laying in a field near the county line who had lost control of his motorcycle. Due to injuries received in the accident, the decision was made to fly him to Shock Trauma via MSP Trooper 1. The motorcycle was a total loss, and wound up several hundred feet from where the patient was located. The Maryland State Police are investigating the accident to determine the cause.
