A landscaper who said Kyron Horman's stepmother offered to pay him to kill her husband about six or seven months ago went back to Terri Moulton Horman on June 26 at the urging of police.
This time, he wore a body wire and was accompanied by an undercover officer. On the recorded conversation, he sought $10,000 from her, saying otherwise he would go to police with the murder-for-hire plot, sources said.
Terri Horman apparently cut off the conversation fairly quickly, sources said.
She is the last person known to have seen Kyron, a second-grader at Skyline School, before he disappeared June 4. Large-scale searches found no sign of the 7-year-old.
Authorities deemed the landscaper's account credible and serious, and they shared it with Kyron's father, Kaine Horman, the same afternoon of the undercover operation.
The landscaper's account prompted Kaine Horman to leave his wife and take their 19-month-old daughter. Within two days, he obtained a family law attorney and filed divorce papers and a petition for a restraining order against his wife.
