AUGUSTA -- Authorities dropped an arson charge against a man who had been accused of starting a fire at the former Waterville Boys & Girls Club after he pleaded guilty Thursday to other charges connected to the incident.

Calvin G. Pratt, 20, of Carmel, pleaded guilty to burglary and criminal-mischief charges. He was one of five adults and four juveniles charged with setting a fire March 20 in a pool in the vacant building.

A series of burning objects were thrown inside the pool area, video recorded, set to music and posted on YouTube with a list of credits. A parent of one of the juveniles saw the video and reported the incident to police, according to information offered at other court proceedings.

Pratt's hearing in Kennebec County Superior Court was continued for sentencing, and he has an opportunity to withdraw his plea to burglary if he successfully completes the terms of a deferred-disposition agreement.

The terms include doing 250 hours of community service, and avoiding contact with the codefendants in the case. He also was ordered to serve 25 days in jail for the criminal-mischief conviction, a misdemeanor offense which will remain on his record, according to his defense attorney David Crook.

If Pratt violates the agreement, the burglary conviction will remain and he could be sentenced to a maximum of five years in jail, Crook said.

Crook told Justice Nancy Mills that Pratt had a minimal role in the illegal activity. "He came to Waterville one weekend and he went along one night," Crook said. "According to my client, he is the only person who stayed and made sure the fire was out."

Pratt was the first of the adults to plead to his involvement in the case. Three other juveniles also admitted to committing felony burglary in connection with the same incident.

"All the juveniles in the cases handled so far got suspended sentences," District Attorney Evert Fowle said on Thursday. They were placed on probation after hearings in June in Waterville District Court and ordered to do 200 hours of community service.

All four were ordered to contribute to $336.40 restitution. Crook said that money paid for materials and labor for boarding up the club "which should have been done a long time ago," he said.

The property is owned by Northern Ventures LLC.

Arson and burglary charges are pending against Scott Andrew Thrasher Jr., 17, of Waterville. He is due to appear in Waterville District Court again Aug. 11.

Arson, burglary and criminal-use-of-explosives charges are pending against four other adults: Nicholas J. Laws, 19, and Zachary X. Babb, 22, both of Winslow; Joseph P. Church, 20, of Fairfield, and Jesse Robert Ferran, 19, of Waterville.

Ferran also is charged with two counts of arson for an incident March 19 on property belonging to the Waterville Parks and Recreation Department.

All the men are scheduled to be in Kennebec County Superior Court on Sept. 2.
