Adam Fine, 21 of Cornville was killed yesterday when the roof of his mobile home, which was in the process of being demolished, collapsed under the weight of snow on the roof. Authorities say a second man, Nathan Shaw, 22 of Skowhegan, was also in the trailer when the collapse occurred. Shaw was taken to Redington-Fairview General where his injuries were not considered to be life-threatening. The roof collapse was not only aided by the weight of the snow but also due to the interior walls of the trailer, which often provide extra stability, had been removed.
