Alexander Rismoen was three years old when he was last seen in Phoenix on August 14, 2024. He is described as a white male child with blond hair and brown eyes. Alexander disappeared the same day as four-year-old Mia Rismoen; the two cases have been publicized together.

Public information states the children were abducted by a non-custodial relative, but does not identify that person, explain the exact relationship, or describe the events immediately before the abduction. No publicly disclosed details name an address or neighborhood where Alexander was last seen, what he was wearing, what transportation was used, or where the children may have been taken.

Advocates and missing-child organizations continue to circulate the cases and ask anyone with information to contact the Phoenix Police Department at 602-262-6151. If anyone knew Alexander, saw him after August 14, 2024, or has information about the non-custodial relative, please contact Phoenix police.
