DETROIT -- Families of at least 77 people killed in crashes caused by defective General Motors ignition switches will get compensation from the company.

Attorney Kenneth Feinberg, who was hired by GM to compensate victims, updated the total Monday. It was up from 74 last week.

An additional 141 injured people also are eligible for compensation.

The fund received a total of 4,342 claims by the Jan. 31 deadline. Of those, 1,263 are still under review. Feinberg says more than half are ineligible or lack documentation.

GM knew about problem switches in Chevrolet Cobalts and other small cars for more than a decade but recalled them only last year. They can slip out of the "on" position, which cuts off the engine, knocks out power steering and turns off air bags.
