Police say 50-year-old Corenthea Skipwith is facing charges after she lost control of her SUV and crashed on County Road 83 in Farmingville Wednesday afternoon.
Her 15-month-old granddaughter, Terrayjah Burwell, was ejected and died at the scene. Police say the child was in a car seat, but it was not properly restrained.
Police issued Skipworth summonses for driving without a license, suspended registration, uninsured vehicle and improper child restraint.
Skipwith and the child's mother were hospitalized for non-life threatening injuries.
Two hours later, an elderly Huntington man was killed in West Hills after the car he was driving crossed over into another lane on Round Swamp Road and struck an oncoming vehicle.
Police say 85-year-old William Holden was later pronounced dead.
The other driver sustained non-life threatening injuries.
