On Monday, Winston McKay was walking his dog on an upper Manhattan sidewalk when he was hit in the leg by a bullet. He died hours later. Now police have released footage of the person they say is responsible for the shooting. He's wanted for murder.

According to the NYPD, around 2:21 a.m. on June 10th, a person pointed a rifle at a 26-year-old man on the sidewalk in front of 501 West 146th Street in Hamilton Heights, but the man ignored the guy holding the rifle and continued to walk down 146th Street. Then police say the gunman "then fired once at the male and missed him. That fired round struck the 40-year-old male victim in the right leg as he walked his dog in the vicinity of Amsterdam Avenue and West 146 Street."

McKay was taken to Harlem Hospital, where he died.

The Daily News says that the bullet hit McKay's femoral artery. McKay and his husband Terry Solomon had celebrated their 18th anniversary hours earlier; Solomon told the News, "They tell you to remember the good times, the fact that we had 18 years. But I was robbed of another 18 years with the person I loved. And now I have to go to a funeral and say my final goodbye."

Police released video of the suspect, who was described as being about 18-25 years old and 5'8"-5'10" tall with braid. He was last seen wearing a red hooded sweater, a blue jacket, gray sweatpants, and black and white sneakers.
