An Amber Alert issued out of Delaware County, Okla., has been canceled after the two children were found safe in Arkansas.

According to the sheriff's office, 2-month-old Maxwell Keener and 20-month-old Adelyn Keener were believed to have been taken by their mother, 31-year-old Sarah Jane Lewis.

The sheriff's office says the children were in danger in Lewis' care because she's a known methamphetamine user.

They were last seen in Payne County.

The Amber Alert was canceled shortly before 2 p.m. Thursday after the children were found safe in Pineville, Ark.
