WISCASSET — A Belfast woman was in jail Thursday following her arrest two days earlier in connection with an alleged road rage incident on Route 1 in Wiscasset, the town’s police chief said.

Based on witness accounts, police interviews and a drug test, 26-year-old Elizabeth Brown was charged with driving to endanger and leaving the scene of an accident, Police Chief Troy Cline said Thursday.

During his investigation, Cline also discovered that Brown was on probation. She tested positive for Suboxone, for which she has a prescription, and an amphetamine, for which she does not. She was taken to Two Bridges Regional Jail in Wiscasset.

The confrontation began around 9:45 a.m. Tuesday when 61-year-old Leverett Davis of Freeport saw Brown’s vehicle approaching in his rearview mirror at high speed, Cline said. Davis told police he avoided her by moving to the center line while Brown passed him in the righthand breakdown lane.

When Davis sped up to get her license plate number, Brown slammed on her brakes, the cars collided, and she sped off, police said.

Davis continued to follow, honking his horn to try to get her to stop, he said. Brown braked suddenly in front of the Wiscasset town office, causing the cars to collide again. Brown then gave Davis an obscene gesture and drove off, Cline said.

On Route 1 in Wiscasset, Davis flagged down a deputy from the Lincoln County Sheriff’s Office, who stopped Brown in Edgecomb. Sgt. Jason Nein escorted both drivers to the Wiscasset police station.

Cline interviewed both drivers and found a partially full bottle of Bacardi 151 rum in Brown’s car.

“It could have been a deadly situation if she had not been stopped by police,” Cline said.
