The former husband of Lisa Montgomery says he threatened to expose her lies about being pregnant and to take away custody of their children, just days before she went to Skidmore, killed Bobbi Jo Stinnett, and cut the woman’s baby from her body.

Ex-husband Carl Boman knew Montgomery had gotten her tubes tied in 1990.

Montgomery’s present husband says he was convinced she was pregnant and did not think it was strange that she wanted to go home just six hours after supposedly giving birth in a birthing center in Topeka.

Today is the fourth day of Lisa Montgomery’s trial.
