Eric Frein, the fugitive suspect in the shooting attack on two Pennsylvania State troopers that killed one, has been captured after a 48-day manhunt. Here's a timeline of the events that led to his capture.

Sept. 12: During a shift change at Blooming Grove Township barracks in Pennsylvania, shots were fired by an unseen gunman. During the attack, Cpl. Bryon Dickson, 38, of Dunmore, a seven-year veteran of the force, was killed and Trooper Alex Douglas was wounded.

Sept. 15: Police find a vehicle partly submerged in a lake a few miles from the crime scene, containing shell casings that matched those used in the shooting of the two officers, plus other military-style equipment.

Sept. 16: Authorities identify Matthew Eric Frein, 31, described as “extremely dangerous” and an anti-law enforcement survivalist, as the main suspect in the shootings. State Police Commissioner Frank Noonan told a news conference Frein had “made statements about wanting to kill law enforcement officers and also about wanting to commit mass acts of murder.”

Sept. 18: The FBI adds Frein to its “Ten Most Wanted” list. The funeral of Cpl. Bryon Dixon is held in Pennsylvania.

Sept. 20: Police surround a cabin in Barret Township belonging to Frein's parents, and officers block roads in the area and urge residents to stay indoors. Police believe they are closing in on Frein, but no arrest is made.

Sept. 21: Police find an AK-47-style assault rifle and several magazines of ammunition in a deeply wooded area around Canadensis, Pennsylvania, which they believe Frein concealed there. Police say the find is in line with their thinking that Frein had been planning the attack for months, or possibly years. At least 400 officers from multiple law enforcement agencies are now involved in the hunt for Frein.

Sept. 28: Police reveal that they have found soiled diapers -- a kind used by professional marksmen who must remain still for long periods of time -- and Serbian cigarettes during their pursuit of Frein. Officers claim to have seen the fugitive in the distance, but he managed to evade capture.

Oct. 8: Police hunting Frein discover a diary believed to belong to the fugitive. In it he details the attack on the two troopers. A chilling passage from the document reads: “Got a shot around 11 p.m. and took it. He dropped. I was surprised at how quick. I took a follow-up shot on his head, neck area. He was still and quiet after that. Another cop approached the one I just shot. As he went to kneel, I took a shot at him and jumped in the door. His legs were visible and still.”

Oct. 17: A woman reports a possible sighting of Frein near the eastern Pennsylvania town of Siftwater. She describes a man armed with a rifle whose face is covered in mud. Up to 1,000 law enforcement officials have now been involved in the search for Frein.

Oct. 27: Police employ a drone-style unmanned balloon, equipped with high-resolution cameras, in their search for Frein.

Oct. 30: Frein is captured, reportedly in an abandoned hanger at an airport in the Pocono mountains. No shots were fired during his arrest. He was on the run from authorities for 48 days.
