Former Blink-182 drummer Travis Barker and a popular disc jockey were critically injured in a Learjet crash in South Carolina that killed four people, authorities said Saturday.

Federal Aviation Administration spokeswoman Kathleen Bergen said the plane carrying six people was departing shortly before midnight Friday when air traffic controllers reporting seeing sparks. The plane went off a runway and crashed on a nearby road, she said.

Hospital spokeswoman Beth Frits said Barker and DJ AM, whose real name is Adam Goldstein, were in critical condition at a burn center in Augusta, Ga., about 75 miles southwest of Columbia.

Two other passengers and two crew members died, said the National Transportation Safety Board. Their identities were not immediately available.

Barker and Goldstein, who perform together under the name TRVSDJ-AM, played a free concert in Columbia's college neighborhood Friday night.

"It's absolutely terrible and tragic," Columbia Mayor Bob Coble said.

A representative for Barker and DJ AM said she had no information the crash.
