A Long Island woman is accused of killing her 2-year-old twin daughters.

Police received a 911 call of a possibly suicidal woman around 2:30 p.m. on Thursday. The caller told the operator that 24-year-old Tenia Campbell was threatening to kill herself and her twin daughters.

Authorities conducted a county-wide search between Medford to Montauk when they found Campbell’s vehicle at a Montauk park around 4 p.m. — 60 miles away from their home.

The children, later identified as Jasmine and Jaida Campbell, were inside the vehicle in cardiac arrest and were taken to Stony Brook Southampton Hospital where they were pronounced dead, police said.
