Police suspect the 26-year-old man was the target of a gang hit.
Police say White and his uncle were shot in the head while riding in a vehicle with his uncle's girlfriend. The child was pronounced dead at a hospital. The woman, who is the toddler's aunt, is in fair condition at Mt. Sinai hospital.

After about three minutes, gunshots ring out and the expectant mom can be seen running out of the vehicle. The entire encounter was shockingly recorded on Facebook Live, and even more devastating, Lavontay is the 3rd child to get shot in Chicago this week alone - the 2nd to die.
Police did not immediately release information about the circumstances of the shooting.
Two people were killed, including a toddler, and a third person was critically wounded in a shooting Tuesday afternoon in North Lawndale. Relatives told the newspaper she was about four months pregnant and is expected to survive.
"Call 911! They killed him.I have a bullet in my stomach". Two girls ages 11 and 12 were shot in the head by gunmen who were aiming at someone else, in an area of the city known for heavy gang activity. Both girls were in critical condition on Monday but police have not updated their condition since.
Chicago Mayor Rahm Emanuel has said he would welcome federal help and additional funding to complement the efforts of local law enforcement. Devonte, who is pregnant, was also shot in the stomach.
"They just don't fear it, and until we create that mental accountability to them to not pick up a gun, we're going to continue to see this cycle of violence", Mr Johnson said.
