The discovery of bones on an island on the Mohawk River turned out to be the remains of an animal, Amsterdam Police announced on Friday.
Police in a release said two siblings were kayaking on the river just east of Lock E-10 on Wednesday when they stopped to rest, found the remains and took photos.
A doctor told the pair he thought the bones may be human remains so the youths reported it to police.
The Amsterdam Police, Fire department and Montgomery County Sheriff's department's boat patrol all went to the scene, recovered the bones and had them analyzed.
County Coroner Joseph Rile and forensic pathologist Dr. Michael Sikirica determined the bones are likely those of a cow.
Police said there is one active missing person case in the city, that of Robert Wiltsie, who was reported missing Oct. 17, 2010. That case is still active, police said.
