The Latest on the disappearance and presumed slayings of an Arlington, Washington, couple (all times local):

12 a.m.

Court documents released Monday say that a man wanted in connection with the disappearance and presumed slayings of a married couple previously threatened to shoot them for cutting brush between their two properties, the Seattle Times reports (http://bit.ly/1rdrkgp.)

The Times says that John Blaine Reed, 53, who shared a common driveway with Patrick Shunn and his wife, Monique Patenaude, "reportedly stated he would shoot or assault them if they didn't leave" him alone, investigators wrote in an affidavit for a search warrant.

The newspaper says that Reed's alleged threat, which Shunn later reported to Snohomish County sheriff's deputies, was just part of an "ongoing and constant" dispute between the couple and Reed.

Patrick Shunn and Monique Patenaude worried about getting on the wrong side of the man who lived a little ways up an old logging road from their 21-acre spread along the Stillaguamish River.

When they sued other neighbors over a property dispute more than two years ago, they avoided naming him as a defendant because they didn't want to irk him, their former lawyer said Monday.

But now the couple is missing and presumed murdered, and investigators are trying to track down the man, John Blaine Reed, 53, along with his brother, Tony Clyde Reed, 49. Snohomish County Sheriff Ty Trenary said surveillance video linked them to the dumping of the victims' cars over an embankment in a remote, wooded area near Oso, about 50 miles north-northeast of Seattle.
