The body thought to be of Samantha Koenig, the 18-year-old teen barista from Alaska who went missing Feb. 1, was found on Monday at a crime scene investigation in Matanuska Lake near Anchorage.

Police Chief Mark Mew announced on Monday that the body believed to be Koenig was recovered during an investigation dive by Alaska Police, State Troopers and the FBI.

I can only reiterate and again assure you our joint decisions to not release more information were driven exclusively by our desire to maximize the potential for Samantha Koenig's safe return, Mew said as reported by WSBT. Unfortunately, that potential no longer exists.

Alaska state medical examiners will identify the body.

Mew said that police believe she was murdered briefly after she went missing.

Investigators believe Samantha died within hours of her abduction, and we are continuing to investigate these facts, Mew said. Investigators further believe the person responsible for Samantha's death acted alone, and we are confident that we have that person in custody.

Authorities arrested a person of interest named Israel Keyes, a 34-year-old man who owns a construction company in Anchorage, in March in Lufkin, Texas and he was arraigned on March 27 in federal court.

Keyes pled not guilty to a charge of access device fraud after making cash withdrawals from a stolen debit card, though it did not belong to Koenig.

We are working closely with the U.S. Attorney's Office, and charges for Samantha's kidnapping and murder will be forthcoming, Mew said.

Police are looking for more information about Keyes, who was driving a white Chevrolet pickup truck when he was arrested,

We would like to reiterate our request for information relative to the movement of the white pickup truck, FBI Special Agent Mary Rook said Monday, according to The Associated Press. Specifically, we want to hear from anyone who may have seen the truck in the vicinity of Matanuska Lake.

Koenig went missing on Feb. 1 and was last seen on footage from a surveillance camera being forced away from the coffee shop she worked at with an armed man. Detective Slawomir Markiewicz did not address whether or not Keyes looked like the man seen in the video.

Since the footage was reviewed by police, her family and countless members of Koenig's community have posted flyers in the search for missing barista Samantha Koenig.

According to the Associated Press, Israel Keyes served in the Army for three years before starting his own construction business in Alaska in 2007.
