Marcos Huallpa, 46, was shot dead inside his car on the evening of January 20, 2015, around 10:15 p.m. The shooting took place outside 188 Sand Lane in the South Beach neighborhood of Staten Island. Huallpa, a resident of Queens, was taken to Staten Island University Hospital North, where he was pronounced dead.

Early reports say Huallpa had arranged to meet a woman by phone and that a dispute with another man at the scene escalated into the fatal shooting; the shooter reportedly fled in a white Honda CRV and the woman was said to be cooperating with police. Alternate accounts describe the killing as tied to a turf dispute between rival prostitution crews and identify the shooter as an alleged enforcer for a competing operation.

No arrest, charge, or conviction is publicly documented for this homicide, and the case appears on lists of unsolved Staten Island killings from 2015. If anyone has information about that night or about the white Honda CRV seen at Sand Lane, please come forward.
