Federal safety investigators are taking a rare look at a crash that killed five bicyclists in southwestern Michigan.

Eric Weiss, a spokesman at the National Transportation Safety Board, says investigators were at the scene Thursday. He says the NTSB's highway safety staff could make recommendations to prevent a similar tragedy.

Weiss said Friday that it's been decades since the agency has "looked at bicycles and cars and safety."

Five bicyclists were killed and at least four were injured Tuesday when a pickup truck struck the group from behind on a two-lane road in Kalamazoo County's Cooper Township. The driver, Charles Pickett Jr., is charged with second-degree murder.

One of the injured was in serious condition Friday. The other three were fair or good.
