The blood alcohol level of 20-year-old Island woman Brandy Gibson was over twice the legal limit when she was killed in a motor vehicle accident at the intersection of Edgartown-Vineyard Haven and County Roads on Jan. 29, according to a toxicology report released this week by the Oak Bluffs police.

A press release from the Oak Bluffs police, who had been waiting on the results of the toxicology report from the Office of the Massachusetts Chief Medical Examiner before closing its investigation, stated that Ms. Gibson’s blood alcohol level was .19 at the time of the crash. The legal blood alcohol limit for a driver over the age of 21 is .08.

Police also said the toxicology report indicated a presumptive positive result for marijuana. Police are citing Ms. Gibson’s speed of 82 miles per hour as the primary cause for the crash, and her level of intoxication as the second contributing factor.

According to police, Ms. Gibson was traveling west towards Vineyard Haven on the Edgartown-Vineyard Haven Road around 10:30 p.m. when her car struck a Humphreys bakery delivery van driven by Francellyo C. Dias, who was turning left toward Edgartown at the time.

No one involved in the accident was wearing a seat belt, police said.

Ms. Gibson later was pronounced dead at the Martha’s Vineyard Hospital. Mr. Dias, 25, of Vineyard Haven, and his passenger, Lessa Keila, were flown to Brigham and Women’s Hospital in Boston and later released following treatment.

An accident reconstruction conducted by the Massachusetts state police found that Ms. Gibson’s vehicle left a single skid mark measuring 67 feet long, and that her estimated speed upon impact with the van was 73 miles per hour.

The delivery van was traveling at 9 miles per hour at the time of impact, which is consistent with someone starting or turning from a stop, the reconstruction found.

In his final report of the accident, Oak Bluffs officer James Morse noted that Mr. Dias did not have a driver’s license at the time of the crash but also concluded he was not at fault in the crash.

“[Mr.] Dias did not possess a valid driver’s license at the time of the crash. Other than his license status, he complied with all other motor vehicle laws and regulations at the time of the crash,” officer Morse wrote.

Oak Bluffs police have requested a criminal complaint against Mr. Dias for unlicensed operation of a motor vehicle.
