According to the Spokane County Sheriff's Office, law enforcement have located Amber Alert suspect Justin Robertson in a home in St. John, WA.

At this point, authorities say Robertson is inside a home there, and they have been in contact with him. They are asking him to surrender, but at this time that has not happened. Authorities say that they do not have specific information about his 5-year-old son, but Ethan Robertson is believed to be alive.

Authorities are asking that everyone avoid the St. John area as they work to resolve this situation as quickly, and safely, as possible.

Robertson is believed to have abducted his son, after stabbing his estranged wife at her Spokane Valley home Tuesday morning. Melissa Robertson, according to deputies, is expected to survive.
