A Learjet crashed shortly after takeoff last night killing four of the six people on board. The incident, which happened at an airport in Columbia, SC, also injured former Blink-182 drummer Travis Barker and friend DJ AM (a.k.a. Adam Goldstein).

Barker, also known for his MTV show Meet the Barkers, and Goldstein, Nicole Richie‘s former fiancee, were both taken to an Augusta, GA hospital. The two men were last listed in critical condition and were reportedly being treated for burns.

Those killed in the incident include Barker’s 29-year-old assistant, Chris Baker, and his 25-year-old security guard, Charles Still. The pilot, 31-year-old Sarah Lemmon, and co-pilot, 25-year-old James Bland, were also killed.

Travis and Adam, who appear together under the name TRVSDJ-AM, had just wrapped up a concert near the University of South Carolina. (Perry Ferrell, lead singer of Jane’s Addiction, and Gavin DeGraw were also performers at this free event.) Their plane was heading back to Van Nuys, CA when it crashed through a fence off the side of the runway shortly before midnight.

The NTSB is currently investigating the circumstances behind the “overrun.” Weather is not believed to be a factor in the incident.
