On April 12, 2012, Richard Belisle and James Hopkins were killed while working at a Coast Guard station on Kodiak Island. Nearly a month later, the FBI has not named a suspect, and yet maintains that the community is not in danger.

Not much is known about the details of the April 12 killings. Those investigating -- the Coast Guard, the Alaska State Troopers, agents from Homeland Security, and the FBI -- have kept information tight.

Here is what is known: A house belonging to Kodiak residents James and Nancy Wells was searched after the shootings. Their cars were reportedly searched.

James, a former member of the Coast Guard, worked at the rigger building as a civilian. He, like Hopkins and Belisle, repaired antennas.

Authorities have said nothing about James.
