Jonathan Santana, 26, was shot on East 163rd Street in the Bronx just before 12:30 p.m. on September 1, 2014. Police and emergency responders found him with gunshot wounds to his arm and chest; he was taken to Lincoln Hospital but was pronounced dead on arrival.

The NYPD opened a homicide investigation after the daylight shooting outside a residence. Detectives canvassed the block and pursued leads, but early efforts were described as challenging. No arrests have been publicly announced and no suspects have been identified.

Does anyone who was on East 163rd Street that afternoon or who knew Jonathan have information that could help bring answers?
