Clatsop County authorities arrested 20 people in connection with a major drug investigation in the Seaside area.
The six-month investigation, dubbed "Operation Pandora's Box," led police to three separate places. One of them was a complex along Highway 26, which included a home with six trailers surrounding it.
Detectives say they seized meth, heroin and more than $2,500 in cash while serving search warrants on Sunday. Among those arrested, detectives say there was a mother and daughter pair, along with two pairs of fathers and sons.
