( NewsNation) — Montana officials said the search for the suspect in a deadly bar shooting is expanding as it enters a sixth day. Officials did not give specifics on where the search has expanded but said there are several local, state and federal teams taking part in efforts.

Many manhunts end quickly, but the man accused of killing four people in rural Montana appears to have disappeared into the kind of wilderness that helps elude pursuers.

A manhunt for Michael Paul Brown has been underway since Friday morning, when four people were shot and killed in the town of Anaconda.
