Lawrence-Douglas County Fire and Medical personnel watch an air ambulance take off Friday morning from the parking lot of Hobby Lobby on 23rd Street. The air ambulance was carrying Sean Ragan, a 19-year-old male victim of a fall from a third-floor balcony at Campus Court at Naismith apartments, 1301 W. 24th St.

Lawrence police are trying to determine why a 19-year-old man fell early Friday morning from a third-floor apartment balcony.

Residents of the Campus Court at Naismith apartments, 1301 W. 24th St., said they awoke early Friday morning to a loud thud, followed by a lot of noise.

When they looked outside, they discovered a tenant of a nearby apartment had fallen from a third-floor balcony to the pavement below.

Police identified the victim as Sean Ragan, a resident of the complex.

Lawrence-Douglas County Fire & Medical workers and police were called just before 5:30 a.m. to Building K at the apartment complex.

Police said they were originally called in response to a disturbance. When they arrived, they found Ragan on the ground, approximately 25 feet below the third-story balcony.

One woman, a nearby tenant who lives on the second floor, said she was an emergency medical technician in the military so she rushed to help. She said the man was in shock and appeared to be suffering from a head injury.

Kansas University spokesman Todd Cohen confirmed that Ragan is the son of Ron Ragan, associate dean for academic affairs at KU’s School of Pharmacy.

Ragan was flown to Kansas University Hospital in Kansas City, Kan., by a helicopter ambulance. Late Friday night, the hospital still was not releasing Ragan’s condition.

Police said the investigation into what caused the fall from the balcony is ongoing.
