A 16-year-old boy was fatally shot Monday afternoon in St. Paul's Payne-Phalen neighborhood, and police on Tuesday arrested a teenage suspect.

The Ramsey County Medical Examiner's Office identified the deceased as Antwan Watson of St. Paul. His death marks St. Paul's 28th homicide of the year.

Officers went to an alley in the 1000 block of E. York Avenue about 12:30 p.m. and found Watson suffering from apparent gunshot wounds, said Sgt. David McCabe.

St. Paul paramedics arrived and pronounced Watson dead at the scene, McCabe said.

Investigators spent Monday afternoon canvassing the neighborhood looking for witnesses and evidence. On Tuesday morning, police arrested a 16-year-old boy near the intersection of 5th and Minnesota streets in connection with the shooting.
