The Bucks County Courier Times reports a judge sentenced 19-year-old Tatyana Henderson to one to two years in prison.
Henderson served as a lookout when Danny DeGennaro was fatally shot at his Levittown home in 2011. She was 17 then, but was charged as an adult.
A woman charged as a juvenile also was sentenced on Tuesday. She'll continue serving time at a youth detention center for at least six more months.
The women testified against co-conspirators Jermaine Jackson, Breon Powell and Kazair Gist. They told jurors that Jackson recruited them to help "get money" from DeGennaro.
Jackson and Powell are serving life terms. Gist will be sentenced next week.
