The lone suspect in the case, Israel Keyes, is being held in Alaska on federal fraud charges.
Anchorage Police Chief Mark Mew said city police, state troopers and FBI agents spent hours at the lake searching for clues. "Investigators believe Samantha died within hours of her abduction," Mew said.
Koenig's abduction set off a massive search. Family members distributed and posted thousands of flyers throughout Anchorage offering a reward for information. Her kidnapping also prompted baristas in the numerous coffee shops in Anchorage and throughout Alaska to begin taking self defense classes.
A Random Abduction?
During the course of the investigation into Koenig's disappearance, authorities arrested Keyes in Texas. The 34-year-old owner of an Anchorage construction company was returned to Alaska to face charges in connection with making cash ATM withdrawals with a stolen debit card. The card did not belong to Koenig, police said.
"Investigators further believe the person responsible for Samantha's death acted alone, and we are confident that we have that person in custody," Mew said.
Friends and family members said Koenig did not know Keyes and he had no connection with anyone in her family. They believe her abduction was completely random.
Investigators are seeking witnesses who may have seen Keyes' white Chevrolet pickup truck with green tool boxes in the vicinity of Matanuska Lake or the midtown coffee shop where Koenig worked in late January or early February.
