"I'm sorry for taking her away from everyone," Christopher Lockhart wrote on a map to his wife's body
. "I had no right to do what I did." Police in Portage, Mich., have released around 200 pages of documents related to the death in May of Theresa Lockhart and Christopher Lockhart's suicide
in October, Fox 17
reports. Those documents include Christopher's suicide note
, in which he admits to and apologizes for killing his wife, and the map to her body. In his suicide note, Christopher says he killed Theresa by choking her to death while drunk after he "snapped" during an argument. He also apologizes for killing their cats, according to WOOD
. The map bears instructions to "find her and put her to rest." MLive
reports police found Theresa's body less than a minute after beginning a search of the area shown in the map.
The newly released documents also detail Christopher's apparent disinterest in the disappearance of his wife. "Well, she's a grown adult," he told police a week after he killed her. "If she wants to take off and leave, she can do that." Multiple women say Christopher reached out to them on dating sites around the time his wife was reported missing in May. One woman says "he laughed and joked when he talked about his wife being missing," which she thought was inappropriate. Another woman says she texted Christopher on what would be revealed to be the night he killed Theresa; he texted back that he was "buzzed" and horny. Other details in the documents include the results of searches of the Lockharts' house, including a book on "unexplained disappearances." (Read more murder stories.)
