The Westbrook Police Department said in a Facebook post an officer patrolling the Riverbank Park area spotted the "large snake" about 3:30 a.m. Wednesday "eating a large mammal, possibly a beaver (not joking)."

The Maine Warden Service advised the department that the snake, estimated to be at least 10 feet long, is likely to "remain dormant" for the next few days while it digests its meal. The department asked the public to keep a lookout for the snake, nicknamed "Wessie" and the "Presumpscot Python" by locals.God I think I ate too much for breakfast. Going to take about a two day nap.
