HERMON, Maine — A fight between a mother and daughter Monday night caused the mother to become distracted while driving, and she crossed the centerline and crashed head-on into the car of a Carmel woman, killing her on impact, Deputy Chief Troy Morton of the Penobscot County Sheriff’s Office said Tuesday.

Karen Worcester, 60, of Carmel died at the scene of the two-vehicle crash that occurred at about 5:40 p.m. on Route 2 just before the Carmel town line, the deputy chief said.

Rebecca Chasse, 52, of Carmel was driving a 2003 Jeep Liberty with her daughter Rachelle Welch, 29, of Carmel as her passenger. Chasse’s Jeep stuck Worcester’s 2012 Ford Fusion shortly after crossing into Hermon.

“Mrs. Chasse became distracted while having an argument with her daughter,” Morton said. “[Chasse], who was traveling toward Hermon, crossed the center line and struck Karen Worcester’s vehicle.”

Chasse and Welch were taken to Eastern Maine Medical Center and St. Joseph Hospital in Bangor with serious injuries, Morton said Monday night. A spokeswoman from St. Joe’s and a spokesman from EMMC both said Tuesday that they had no information about the conditions of either the mother or daughter.

Whether Chasse will face any charges will be up to the Penobscot County district attorney’s office, Morton said.

“The investigation is ongoing. Once completed it will be reviewed with the district attorney’s [office],” the deputy chief said.

Route 2 was temporarily closed to traffic for the investigation led by Sgt. Jamie Kennedy and Detective Andrew Whitehouse. Maine State Police, firefighters and rescue crew members from Hermon, Carmel and Levant also assisted at the fatal crash scene.

Worcester was a grant supervisor in corporate accounts for Eastern Maine Healthcare Systems and had worked for the finance department since 2005, spokeswoman Suzanne R. Spruce said Tuesday afternoon.

“There is a lot of sadness here today,” she said.

Many of Worcester’s co-workers are stunned and shocked by what happened, Spruce said.

“Karen was a much loved and highly regarded member of EMHS,” she said. “She had a warm smile, incredible sense of humor, and she will be greatly missed.”
