A man who allegedly exchanged gunfire with state police — an incident during which a suspect was killed and a trooper injured — has been charged while recovering from injuries at Hartford Hospital.

The incident occurred on April 8, after an armed robbery at an Old Saybrook motel. The getaway vehicle collided with a state police vehicle on Route 153 in Westbrook, and the suspects and state police exchanged gunfire.

Police Detective Scott Wisner was shot in the shoulder and treated and released from Middlesex Shoreline Clinic. Suspect Jonathan Alvarado, 24, of Deep River died of gunshot wounds. A second suspect, Sebastian Award, also 24 and of Deep River, was transported by Lifestar helicopter to Hartford Hospital for treatment of severe injuries.

On Saturday, police served an arrest warrant on Award at the hospital, charging him with two counts of criminal attempt to commit murder, conspiracy, two counts of first-degree kidnapping with a firearm, two counts of first-degree robbery, three counts of second-degree larceny, three counts of criminal possession of a firearm, assault on a police officer, first-degree reckless endangerment, engaging in pursuit, reckless driving, operating a motor vehicle with a suspended license, interfering with a police officer and aiding and abetting in first-degree assault.

Lt. J. Paul Vance, the state policeman spokesman, declined to explain the kidnapping charge.

On April 8, Old Saybrook Police Department responded to an armed robbery at the Days Inn on Boston Post Road. Officers identified a suspect vehicle leaving the area, and state police troopers responded to assist. The pursued vehicle fled onto Route 153 (Essex Road) into Westbrook, where it collided with a state trooper’s vehicle.

Award remains under guard by troopers and Department of Corrections personnel at Hartford Hospital, where he is being held on $1.5 million cash bond.

If Award is discharged from the hospital this weekend, he would be arraigned in Superior Court on Monday.
