A man died Friday after his car hit a tree. What Sherborn police say caused the accident

SHERBORN — Authorities have identified the man who died in a crash on Western Avenue last week.

Carlos Emilio Esquivel Diaz, 28, of Framingham, died Jan. 26 when he crashed his car into a guardrail and tree, authorities said.

The man was driving at least twice the 30 mph speed limit at the time of the 9:23 p.m. crash, Police Chief Thomas Galvin said Monday.

"It was tough," Galvin said. "The crash was actually witnessed by one of our sergeants, who happened to be in the area at the time."

Galvin said the 28-year-old man was driving a Volkswagen Rabbit from Framingham into Sherborn. The vehicle was moving at between 60 and 70 mph, while the speed limit in the area is 30 mph, the chief said.

"The car lost control and hit a wooden guardrail and slid sideways into a tree," Galvin said.

The car sustained heavy damage, with its driver side androof collapsing. The motorist was declared dead at the scene.

The driver was the only person in the car and no other vehicles were involved, Galvin said.

The crash remains under investigation by the Sherborn police and the Massachusetts State Police assigned to the Middlesex District Attorney's Office.

"We don't know if alcohol or anything else was involved," said Galvin. "We have to wait for toxicology reports."
