Patrick Rosa (19) will spend four months in jail after pleading guilty to reckless conduct and criminal trespassing. The Maine Warden Service says in December 2007 Rosa and three friends were racing snowmobiles on property in Limerick that was closed to the machines. Rosa’s snowmobile struck 42-year old Darrin Smith and his dog, seriously injuring both. Rosa and his friends took off. Smith’s injuries included two broken legs and a broken arm he had to drag himself about 100-feet to a nearby snow bank where his 8-year-old daughter later found him. Rosa called the Maine Warden Service the next night and admitted to the crash.
