( CNN ) -- A body believed to be that of an 18-year-old barista who disappeared in February has been found in a lake north of Anchorage , police in Alaska said . Samantha Koenig was last seen on February 1 being led by a man from the parking lot of the coffee stand where she worked . On Monday , a forensic dive team discovered the body in Matanuska Lake , said Anchorage Police Chief Mark Mew . The medical examiner will conduct an autopsy to confirm the identity . `` Although some questions have been answered today , I know those answers offer little consolation to the Koenig family and that many more questions remain , '' said Mary Rook , the special agent in charge of the investigation . `` I know one question both the Koenig family and the people of Anchorage have asked from the outset is , 'Why Samantha ? ' '' Koenig was taken from the Common Grounds Espresso stand , in the parking lot of an Anchorage fitness club , around 8 p.m. on February 1 . Police said security footage showed an armed man wearing a dark hoodie leading her away . Gone , too , was the cash from the stand 's register , as well as Koenig 's coat , purse and cell phone . Koenig 's family offered a hefty reward for information leading to her return . Friends and volunteers distributed more than 45,000 fliers door to door . The crime struck at one of the hallmarks of the Anchorage community , the tiny coffee stands around town , wrote Daily News columnist Julia O'Malley . `` Coffee shops are a thing here , a signature Anchorage phenomena , '' she wrote in a column on February 9 . `` A study in 2005 said there was a coffee opportunity for every 3,300 residents in the city . At the time , that was the highest coffee-to-person ratio in the U.S. '' On Monday , police said a man , already in custody for an unrelated crime , will be charged with kidnapping and murder . Without naming the man , Chief Mew said he acted alone and that Koenig died within hours of her abduction . Authorities also said investigators found no `` direct association '' between the abductor and Koenig or her family members . The only person listed as a `` person of interest '' in the case is a 34-year-old contractor from Anchorage who was arrested last month in Lufkin , Texas . The man is accused of using a debit card taken from a vehicle on the night of Koenig 's abduction and using it at various locations in Anchorage and also in Arizona , New Mexico and Texas , reported KTUU TV . U.S . Marshals brought him back to Alaska , and he is being held at the Anchorage Correctional Complex .
Samantha Koenig was last seen on February 1 . The search for the missing girl has been called off after a week of fruitless efforts to find her. Police believe her abductor acted alone . They plan to file kidnapping and murder charges against someone already in custody .
