New Delhi, July 30 -- Police in Guyana filed murder charges on Tuesday against the captain and two crew members of a state ferry that capsized, killing more than 70 people, with 30 passengers still missing.

Accused are Captain Kevin Price, 40, chief mate Rondell Dwayne Roberts, 42, and cargo superintendent Delon Granderson, 33. They appeared in court on Tuesday morning but were not required to enter pleas. No attorneys were present for them.

Authorities believe 179 people were aboard the ferry that departed the capital, Georgetown, on July 18 and capsized in Atlantic waters before reaching its destination, the northern town of Port Kaituma near Venezuela. It was the South American nation's worst maritime disaster on record.
