A former Windsor woman has been sentenced to six months in York County Prison and will be under court supervision for four years for the May 2011 crash that killed her mother and son.

Lepree Vonay Christian, 23, was sentenced Wednesday after pleading no contest or guilty last fall to numerous charges related to the crash.

Christian pleaded guilty to two counts of accidents involving death while not properly licensed and pleaded no contest to two counts of homicide by vehicle. She also pleaded guilty to one count each of driving under the influence, driving on a suspended license, and careless driving.

Judge John S. Kennedy also ordered the woman to undergo a drug and alcohol evaluation, counseling, and attend Alcohol Highways Safety Class. She has been ordered to report to York County Prison March 7, and she'll be eligible for work release.

Police said Christian was driving on Windsor Road near Valley Road on May 16, 2011, when she lost control of her Audi on the wet road. The car went off the road and crashed into a tree stump, police said, causing injuries that killed 4-year-old LaShawn Christian and 41-year-old Tamara Christian.

A witness to the crash said she saw the Audi slide toward the opposite lane of travel, then dart "like a rocket" into a ditch, according to court documents.

A second witness said all four of the Audi's tires had left the road prior to the crash, documents state.

An accident reconstruction determined Lepree Christian was driving with a suspended license and was going too fast for the wet road conditions, documents state.

Police allege the marijuana in her system prevented her from recognizing the weather hazard and the curve in the road, with which investigators said she was familiar.
