"We were able to track where the call was made to," Sheriff Stevens said. "I talked to the individuals who received the phone call. There was no conversation over the phone just a silence, and the individual ended up hanging up. It was somebody local, but due to the sensitivity of investigation we don't want to reveal the name. It was someone who didn't know the family, Teresa or Dale, so we don't know if it was a random call or a misdialed number or what have you."
