Cops: Gas found on slain woman's body; suspect bought gas

WORCESTER, Mass. – Police say socks and a hair tie found on the body of a Google employee slain while out for a run near her mother's Massachusetts home tested positive for gasoline, and the man charged with killing her bought $5 worth of gas on the day of her death.

The police affidavit in the death of 27-year-old Vanessa Marcotte was filed in a Massachusetts court.

Marcotte lived in New York City but was visiting her mother in Princeton, Massachusetts, in August 2016 when she failed to return from a run and her body was found in the nearby woods.

Her hands and feet had been burned, ," the affidavit said, "presumably in an attempt to destroy potential DNA evidence."
