( CNN ) -- The stepmother of missing Oregon boy Kyron Horman attempted to hire a landscaper to kill her husband several months ago , CNN affiliates KGW and KATU reported Monday , citing sources with knowledge of the investigation . KGW reported that sources believe the woman , Terri Horman , approached the landscaper , who had been working on the family 's property in northwest Portland , Oregon , and offered the man `` a large sum of money '' to kill her husband , Kaine Horman . Investigators informed Kaine Horman of the murder-for-hire plot and said his wife may have tried to hire others as well , KGW reported , citing sources familiar with the conversation . Terri Horman said she was in a bad marriage and claimed that her husband had `` hurt '' her , according to the sources . The Oregonian newspaper , citing anonymous sources , reported that when detectives confronted her with the allegations , she denied the plot . KATU 's sources confirmed that report . News about the plot could explain why Kaine Horman abruptly moved out of the family home in late June , taking the couple 's toddler daughter with him . He then filed for divorce and was granted a restraining order . A few days later , Terri Horman hired a high-profile defense attorney , Stephen Houze . Calls to Houze by CNN Monday were not immediately returned . Terri Horman has been the subject of intense scrutiny during the investigation into Kyron 's disappearance because she was the last person with him before he vanished on June 4 . However , police have not called her a suspect in the case . She said she last saw the 7-year-old walking down a hallway toward his second-grade classroom at Skyline Elementary School in Portland , according to the police . Kyron 's family has publicly pleaded with his stepmother to provide the police with more information about the boy .
