OREGON CITY, Ore. -- The Clackamas County Sheriff's Office issued a warrant for the arrest of 40-year-old Kelsey McCune on Friday. McCune is believed to have abducted Samantha Dodson, 13, last seen Tuesday night.
Dodson's Oregon City family held a press conference Thursday pleading for her to come home after deputies thought she ran away Tuesday.
"Sammie, your mom and dad are worried about you. Your brothers and sisters are worried about you. Your friends are worried about you and you can't be out there in that cold," said her sister, Sarah Dodson. "Please call us or call 911 and let us know you're safe."
Late Wednesday, the Federal Bureau of Investigation joined deputies in the search for Dodson.
Dodson may be with McCune and she may be in danger, according to Sgt. Robert Wurpes of the Clackamas County Sheriff's Office.
Sheriff Craig Roberts said at the press conference that the two are likely on foot, hitchhiking, or using public transportation. He added that investigators believe the pair is still somewhere between Salem and Southwest Washington.
McCune is reportedly a family friend of the Dodson's and even spent the Thanksgiving holiday with them.
"My biggest concern is Sammy's safety," Sarah Dodson told NewsChannel 8 Wednesday. "It's a shock."
Thursday morning, SWAT crews were called in to back up more in-depth search efforts in Oregon City, Wurpes said.
Search and rescue coordinators were searching the Newell Creek area in Oregon City. Authorities said the two may have camping equipment but are concerned about Dodson's welfare because of record-cold temperatures expected to last for days.
The Clackamas County Sheriff's Office urged news outlets and the public to use the hashtag #FindSamantha on Twitter and Facebook to get the word out on social media.
A new billboard is also going up on McLoughlin Boulevard featuring the latest known photo of Dodson and two more billboards are also planned for Washington County.
Dodson was described as white, 5-foot-4 and 125 lbs., with brown eyes and a slim build. Her hair was recently dyed red.
McCune was described as white, 6 feet tall and 170 lbs., with a glass eye and salt-and-pepper hair. He has no known address.
"I can't imagine her being out on the streets," her sister said.
Anybody who sees Dodson or McCune is asked to call 911 immediately.
