ABC News' Katti Gray reports:
The relatives of a missing 25-year-old Pennsylvania man said they aren't entirely certain they believe in psychics - only that they're willing to use an assortment of means to locate him.
James Slack, of Bridgeville, Pa. was last seen at a String Cheese Incident Concert in Pittsburgh, Pa., on Dec. 6.
"You just explore every option, and anything that can help out is worth it. It's worth a shot," Maureen Shields, Slack's sister, told ABC News' affiliate WTAE Friday while touring the area where her brother was last seen with the psychics.
A friend told police that Slack was inebriated when, during a 3 a.m. phone conversation on Dec. 7, he explained that he was "still partying" and "I don't know where I'm at."
Psychic sisters Suzanne Vincent and Jean Mckenzie Vincent said the visions they've been having and the responses Slack's relatives provided to their queries led them to believe that he is dead.
"I kept seeing a vision of railroad tracks," said one of the Vincents, who, according to their Web site, have been doing psychic profiles and investigations for 25 years.
The Vincents said they had an impression that he was hurt some place and he died from the elements.
In addition to contacting the psychic sisters, Slack's family has been posting pictures of him on social media and on fliers.
"We are doing everything from canvassing, talking to every single person we meet. Actually, we've had fliers handed out to people at concerts from the band," Slack's uncle Michael Lowe told WTAE.
