ELLSWORTH — A former Maine Maritime Academy student whose SUV crashed, killing four fellow students, pleaded not guilty Monday to manslaughter and other charges.

Joshua Goncalves-Radding, 20, of North Babylon, New York, did not speak, except to answer “not guilty” 17 times, once for each charge, during his first court appearance since December’s fiery crash in Castine. Bail was set at $5,000.

Prosecutors believe Goncalves-Radding was driving under the influence and traveling at between 106 mph and 111 mph before the SUV struck a tree and caught fire, according to the indictment.

Killed were Brian Kenealy, 20, of York, Maine; Chase Fossett, 21, of Gardiner, Maine; Luke Simpson, 22, of Rockport, Massachusetts; and Riley Ignacio-Cameron, 20, of Aquinnah, Massachusetts, officials said. Goncalves-Radding and two other students survived the crash.

The indictment issued last month included charges of manslaughter, aggravated operating under the influence, reckless conduct with a dangerous weapon, driving to endanger and one count each of criminal speeding, forgery and unlawful use of a license.
