One man is dead and one man is in critical condition, according to Kansas City Kansas Police.
Officer Thomas Tomasic said at around 11:30 p.m. on Monday night, police received calls of shots fired at 7th and Osage, about three miles from the hospital. Soon after, a man arrived at the emergency ramp of the University of Kansas Hospital with a woman. A spokesperson for the hospital said it was believed that both arrived at the hospital wounded.
The man ran toward the entrance of the hospital and was followed by another male suspect, who shot the victim before turning the gun on himself, killing himself.
"At this time, that first male victim, again life-threatening, is not suspected to make it," Tomasic said.
The woman in the car is being treated for minor injuries. No hospital employees were harmed or nearby during the incident, police said.
Although police had set up squad cars near the entrance as of 3 a.m., Tomasic said the hospital was open and accepting those who needed to get inside. Police are expected to clear the scene soon.
