Donquise Alexander pleaded guilty Thursday morning in connection to the July 2010 Salemtown murder of 14-year-old Vincent Lewis.
Alexander, 16, pleaded guilty to second-degree murder and is expected to serve 100 percent of a 30-year prison sentence, according to a district attorney spokeswoman. Alexander was also 14 years old at the time of the murder.
According to district attorney’s office, Lewis, Alexander and two other teens were outside an apartment building at Sixth Avenue North on the afternoon of July 8, 2010, talking and smoking marijuana.
Alexander left and returned with a rifle, demanding money and marijuana from Lewis. After a struggle with the gun, Alexander shot Lewis several times, killing him immediately.
The other three boys left and went downtown. A maintenance later man found Lewis’ body and called police. Three-weeks later detectives identified Alexander as the shooter, and his mother soon turned him in  to police.
He was later transferred from juvenile court to face the charges as an adult.
That shooting was part of a rash of violent juvenile incidents  in the summer of 2010.
