WELLFLEET — A 47-year-old Eastham woman died when her 2008 Toyota Camry left Route 6 near Old Wharf Road sometime in the early morning of Sunday, Jan. 23. Local and state police are continuing to investigate the cause of the accident of which there were no known witnesses.

Police responded to a report of a wrecked car in a driveway off the highway around 7 a.m. Officers discovered that the driver had been ejected. Juliette Brown, a well-known waitress, bartender, gardener, and mother of four, was pronounced dead at the scene.

The car was totaled. Police say it is certain there were no other passengers in the vehicle.

“It was pretty clear somebody would have been seriously injured,” said Wellfleet Police Chief Michael Hurley this week. “It’s not the type of accident you walk away from.” Hurley said there is also no indication that another vehicle was involved.

The house on the property where the car came to rest is unoccupied and under construction, and other residents in the area did not hear the crash, Hurley reported. Because of the ongoing investigation, Hurley said, he could not disclose who reported the accident or the last person known to have seen Brown alive.

Hurley asked that anyone who may have heard or witnessed vehicle activity on Route 6 near Old Wharf Road between 1 and 7 a.m. on Jan. 23 call the Wellfleet Police Dept. at 508-349-3702.

“Witnesses who may have seen something give us a starting point, but at the moment nobody has come forward,” he said. “Unfortunately, there’s nothing that takes video in that area.”

Evidence at the scene suggests that the car left the northbound lane of Route 6 and rolled over, coming to rest on its side, police said.

“The state police are looking into the mechanics and roadway evidence of the accident, and local police are coming up with a timeline,” said Hurley. The state police report and the medical exam “can take weeks, if not months, depending on the kind of tests they may run.”
