Ocean County prosecutors say a neighbor found 66-year-old Olivia Benito on Sunday morning.
Prosecutors say the neighbour and Benito had attended a benefit together on Saturday night, and Benito had consumed several alcoholic drinks.
The neighbour says Benito stayed at her house for a while after they returned, then left around midnight to go home. The neighbour found Benito the next morning when she went out to clear snow from her car.
Authorities say Benito's death is under investigation.
