(Spartanburg, SC) -- A sheriff is skeptical about a serial killer's claims of more victims.
Serial killer Todd Kohlhepp recently wrote to a reporter that there are more victims investigators don't know about. The revelation came to light in a letter Kohlhepp sent to "Spartanburg Herald Journal" reporter Daniel Gross.
Kohlhepp confessed this year to killing seven people, and Spartanburg County Sheriff Chuck Wright says there is nothing to corroborate Kohlhepp's claims.
