The crash happened around 9:30 a.m. at the intersection of South Cooper Street and California Lane when a car and pickup truck collided.
Police say the pickup truck was heading southbound on South Cooper when it struck Daniel Bingenheimer, who was pushing his son, David, in a stroller and waiting to cross the intersection. The car involved was going northbound on South Cooper Street and trying to make a left on California Lane when the crash took place.
David was pronounced dead at the scene. Daniel was taken to a local hospital with non-life-threatening injuries.
Police say they're not sure who is at fault and they're trying to determine which vehicle had a green light. However, witnesses told FOX 4 on Thursday that the car ran a red light and hit the back of the pickup, causing it to crash into the Bingenheimers.
The drivers of the vehicles involved were also hospitalized with non-life-threatening injuries. The woman driving the car is a mother in her 40s who was going home after getting coffee, her mother told FOX 4.
Daniel's wife, Chelsea, was visibly distraught as she arrived at the scene of the crash shortly after it happened. She is reportedly six months pregnant.
Witnesses said Daniel walked the route with David in the stroller daily and was very proud of his son.
