The last defendant in what Erie Police say was a robbery turned deadly will spend at least the next three decades behind bars for his role in the crime.

David Dalton, 31, was sentenced Friday morning to spend 30 to 60 years in prison for third-degree murder and aggravated assault.

Dalton was among four people who conspired to rob David Tate, 28, along E. 20 St. in June 2017, but it ended in a deadly shooting, police said.

Two of Dalton's co-defendants - Jalen Reynolds, 25, and Taisha Santiago, 27 - are currently serving life sentences for second-degree murder.

Lashonta Dade, 27, testified for the prosecution in exchange for a lighter sentence.
