Authorities search for brothers in couple's disappearance

ARLINGTON, Wash. (AP) - Authorities are searching for two brothers who were involved in a property dispute with a missing Washington state couple.

Neighbors reported Patrick Shunn and his wife, Monique Patenaude, of Arlington missing on Tuesday when their livestock was left unattended and detectives in Snohomish County now believe they were killed.

The Seattle Times newspaper (http://bit.ly/1MD8GYQ ) reports police say they have evidence linking John and Tony Reed to the couple's disappearance and that surveillance video tied them to the disposal of the Shunn and Patenaude's vehicles.

The search for the couple began after their vehicles were found in a wooded area of Oso on Thursday.

Snohomish County Sheriff Ty Trenary says the Reed brothers are considered armed and dangerous.

Authorities found a vehicle that belongs to John Reed in Ellensburg on Saturday.
