The suspect accused of gunning down two officers in Hoonah, Alaska, is under arrest after a nearly 35-hour standoff.

Authorities were still engaged in a standoff with John Marvin Jr., the suspect in the alleged ambush and killing of two Hoonah police officers, as of 7 p.m. Sunday.

A disconnected antenna prevented the emergency device from signaling satellites that a plane carrying nine people, including former U.S. Sen. Ted Stevens, had slammed into a mountainside, according to the NTSB.

The small plane that crashed and erupted in flames Tuesday night near the Susitna River appears to have hit the ground nose down, according to an investigator with the NTSB.

The preliminary report shows onboard device designed to alert rescuers in the event of a crash separated from the plane's mounting bracket during impact. Former U.S. Sen. Ted Stevens was among the five people killed in the crash in Western Alaska.

Pilot Marco Alletto -- one of four people aboard a missing plane in Southwest Alaska -- once used rocks and a pocket knife to fix a propeller bent in a crash, and then refused to call for help after crashing with bear hunters aboard, according to court records.
