VANCOUVER, Wash. -

Police say a 3-year-old boy who was reported missing early Friday in Vancouver may have wandered off.

Spokeswoman Kim Kapp says the boy was found safe at a nearby residence and reunited with his family. Detectives are investigating what happened.

Kapp says a parent left him with a relative overnight at a duplex. The relative woke up about 3 a.m. Friday to check on the boy and found him missing. The door was unlocked.

Kapp says the boy was later found a residence close to where he was staying. He apparently was not harmed. She says police presume he wandered away on his own.
