A passenger in the van was able to escape the gunfire.
Neighbors reportedly heard multiple shots fired and the sound of the minivan crashing into a parked car. The windows of the minivan were blown out.
The gunman fled the scene.
Police say the victim was identified as a longtime neighborhood resident who was about to become a father. His mother recently moved to the South.
It was the seventh homicide this year in Mount Vernon.
Mount Vernon Mayor Clinton Young told police to use whatever resources they need to find the gunman.
"Do not get caught with a gun. You will go to jail, and we will be very aggressive about this now," said Mayor Clinton Young.
Police are going to look at redeployment of officers in Mt. Vernon, bordering the Bronx with a concentration on the guns.
"Guns are to readily available, and young people are to readily eager to posses these guns," said Mt. Vernon Police Commissioner, David Chong.
