Now You Can Help Search For Missing Seattle Hiker Samantha Sayers

A Washington state drone pilot is putting a new twist on missing person searches by asking volunteers to examine images that may offer digital evidence of a hiker who vanished four weeks ago today.

Steve Monchak, owner of PNW Dronetography in Darrington, Washington, is using a Phantom 4 Pro to survey the mountainous terrain of the North Cascades in an attempt to locate Samantha “Sam” Sayers.

The challenge, until recently, was finding enough manpower to scour thousands of images that could hold clues to the whereabouts of the 28-year-old woman, who was last seen on Vesper Peak in Snohomish County on Aug. 1. The solution: Crowdsourcing an army of volunteers online to examine each pixel in Monchak’s drone images.

“The online aspect of this is huge,” Monchak, 39, told HuffPost. “I couldn’t do it alone. After you look through a couple hundred images, your eyes get pretty tired, so these people are a great help. They are finding things and notifying us of unusual objects. It just proves we can all work together on the same project from anywhere.”

The drone allows Monchak to target areas that haven’t been covered by ground searchers or would be exceptionally dangerous to explore on foot.

It’s unclear whether the Snohomish County Sheriff’s Office, which suspended its own search effort on Aug. 23, is aware of the crowdsourcing effort. The agency did not respond to a request for a comment on Wednesday.

The project is similar to a crowdsourcing campaign started after the disappearance of Malaysia Airlines Flight 370. The plane, which was carrying more than 200 people from Kuala Lumpur to Beijing, vanished on March 8, 2014. It is presumed to have crashed in the far southern Indian Ocean.

More than 2 million people examined satellite images of suspected crash locations captured by Colorado-based satellite operator DigitalGlobe. While it’s been reported that some debris has washed ashore in various places, the plane has yet to be found.

Monchak, a former Army soldier who’s typically hired to photograph weddings and real estate, said he’s spent nearly three weeks surveying the mountain. He estimates he’s covered approximately 23 miles of terrain so far.

“I hike up the mountain and can fly out about 3 to 4 miles from where I am standing,” he said. “I can easily cover more area in a day than 100 searchers can, and it’s being done without endangering lives. The drone can cover steep faces of the mountain without having to send someone in on foot, and it can examine crevices without having to have someone rope down them.”

The drone recently captured an image of a jacket in an area nearly inaccessible to ground searchers. The find, according to the missing woman’s mother, Lisa Sayers, proves the value of having a remote-controlled eye in the sky.

“When it was spotted, we used the GPS coordinates to send people out there to locate it,” Lisa Sayers told HuffPost. “It did not belong to [my daughter], but it shows that our volunteer army is working.”

Sam Sayers, described by her family and friends as an experienced hiker, set out on the morning of Aug. 1 for a solo hike in the North Cascades. According to the sheriff’s office, a group of hikers reported seeing her on her way up Vesper Peak around midmorning. Another hiker told police he saw her the same day at the 6,220-foot summit and watched her head south from there.

Sayers was reported missing after she didn’t show up for a 6 p.m. check-in with her boyfriend. Despite multiple searches, authorities have found no clues about where Sayers went after walking away from Vesper Peak. None of her personal belongings, such as her cellphone or car keys, have been located.

Sayers turned 28 on August 13, roughly two weeks after she disappeared. Her mother describes her daughter as a “warrior” who is more than capable of taking care of herself.

“She’s still alive,” Lisa Sayers said. “I put my trust and hope in God and all the people praying for us and helping us.”

Samantha Sayers grew up in Girard, Pennsylvania, a small borough in the Erie metropolitan statistical area. In high school, she was diagnosed with <a href="https://www.webmd.com/skin-problems-and-treatments/guide/alopecia-areata#1" target="_blank" rel="noopener noreferrer" data-ylk="subsec:paragraph;cpos:9;elm:context_link;itc:0" data-rapid-parsed="slk" data-rapid_p="6" data-v9y="1">alopecia</a>, an incurable autoimmune disorder that attacks hair follicles, causing hair to fall out.

Monchak, who’s been donating his time to the search project, said he decided to get involved because he wanted to help Sayers’ family. She grew up In Girard, Pennsylvania, and he grew up in a borough not far from there, he said.

According to Monchak, anyone can help examine the images, which are hosted online. New images will be added on a regular basis, he said.

Monchak estimates that volunteers numbering in the hundreds have spent countless unpaid hours looking at the drone images. He said some volunteers are getting more technical, using photo software to identify specific colors ― namely, items Sayers had with her at the time of her disappearance.

“We know that Sam had gray on and we also know she had some [maroon] on,” he said. “There is a gentleman from Wings of Mercy on Facebook who has a program that can match up colors. We just identified a red object and I will be flying directly to that next because it has really piqued my interest.”

A HuffPost report about Sayers on Tuesday recalled the story of a 66-year-old woman who disappeared while hiking along the Appalachian Trail. She had few supplies, yet somehow survived at least 26 days in the wilderness. Her story and similar stories search and rescue teams have shared with Sayers’ family indicate there is a possibility that she could still alive.

“You can’t just disappear,” Lisa Sayers said. “Until there’s proof otherwise, my girl is out there and we are going to find her.”

With time of the essence, Monchak said he’s making a 4-mile hike up the mountain on Wednesday afternoon. In addition to getting a closer look at the unknown red object, he plans to examine crevices for clues. Like Lisa Sayers, he said he’s not going to give up searching.

“I’m going to continue doing this until she’s found,” He said. “We can see a tennis ball from 150 feet up, so if Sam’s out there, we will see her.”

Kelly Armstrong

Kelly Armstrong, mother of a 2-year-old son, has been missing from Kokomo, Ind., since August 2011. Family members became concerned when they were unable to reach her. A missing person report was filed on Sept. 26, 2011.  In February 2012, authorities charged Armstrong's boyfriend, Travis Funke, with voluntary manslaughter in her death.   According to an arrest affidavit, Funke allegedly told investigators he killed Armstrong around the first of July, placing a plastic bag on her head, wrapping her in a tarp and putting her in a trash tote. The garbage container was supposedly picked up later that same day.  Investigators spent six days sifting through 6,000 tons of trash at the local landfill, but were unable to locate Armstrong's remains.  Armstrong's father, David Armstrong, doubts Funke's version of events.

Robyn Gardner

Robyn Gardner was last seen in Oranjestad, Aruba, on Aug. 2, 2011, traveling with Gary Giordano, an acquaintance she met on a dating website. Giordano claimed Gardner was swept out to sea while snorkeling in waters off Baby Beach. Giordano, 50, allegedly told police he had noticed a current pulling them out to sea and signaled to Gardner that they should return to shore. But when he got to dry land, she was nowhere to be found.   Authorities conducted an extensive search of the area, but were unable to locate the 35-year-old Maryland woman's body. On Aug. 5, police took Giordano into custody before he left Aruba. Authorities held Giordano for four months in Gardner's disappearance, but he was released without charges in early December. Gardner vanished in the same Aruban town where teenager Natalee Holloway disappeared in May 2005. Gardner's whereabouts, like Holloway's, remain a mystery.

William "Billy" Disilvestro

Billy Disilvestro, 28, has been missing since Feb. 7, 2011, when  his grandmother dropped him off at a friend's house in Hamilton, Ohio. At about 2:30 a.m., DiSilvestro placed two calls -- one to his mother and one to his grandmother. Both calls went unanswered. What happened to DiSilvestro after that remains a mystery.  According to police, the friend said DiSilvestro left the house after attempting to contact his mother and grandmother -- presumably for a ride. It is believed he was headed to his grandmother's house about 2 miles away, which would take him through a forested area called Milikin Woods.  Authorities have conducted several searches of the area, but have yet to find any sign of the missing man.  DiSilvestro is described as a white male, 6 feet 2 inches tall, 180 pounds, with black hair and brown eyes. He was last seen wearing jeans and a gray winter coat with fur around the hood. DiSilvestro has several tattoos, including the word SMOKE across his back, Jesus carrying a cross on his upper right arm, and a large angel on his upper left arm.  Anyone with information regarding this case should contact the Butler County Sheriff's Office at 513-785-1300.

Susan Powell

Susan Powell was reported missing by her family on Dec. 7, 2009, when she failed to show up for her job as a stockbroker at Wells Fargo Financial. Her husband, Josh Powell, told police he had been camping with their two children, then ages 2 and 4, and had last seen his wife around midnight. Suspicious of his story, investigators named Powell a "person of interest" in his wife's disappearance. Not long after, Powell and his two children moved back to his hometown of Puyallup, Wash.  On Feb. 5, 2012, police say Josh Powell attacked his two boys, Charlie, 7, and Braden, 5, with a hatchet and then set his home on fire, killing the three of them in a gas-fueled explosion.  Since that time, a mountain of evidence has emerged that supports law enforcement's decision to name Powell the prime suspect in his wife's disappearance. Nevertheless, her whereabouts remain a mystery.
