FORT MYERS, Fla. (AP) - Authorities say a Florida Gulf Coast University student died after jumping from a third-floor balcony at an apartment complex.
    
Lee County Sheriff's deputies say witnesses told them 18-year-old Sean Cavanaugh took an unknown substance before jumping last week. Deputies say Cavanaugh's family decided to take him off life support on Sept. 4.
    
The Fort Myers News-Press (http://newspr.es/QIhBZ4 ) reports that deputies responded to an off-campus student housing complex in Estero after receiving a 911 call.
    
According to a sheriff's report, Cavanaugh threatened others in the apartment and stabbed one of them with a piece of broken glass bottle. He made comments about killing himself before going to the third floor and jumping from the balcony.
    
A university spokesman says grief counseling is being offered to students.
