FULTON, Mo. (AP) — The suspect in the death of a Missouri woman and her daughter last week appears to be trying to disappear and limit the ability to track him, Boone County authorities said.

JT McLean, 45, is charged with two counts of first-degree murder in the deaths of Allison Abitz, 43, and her 11-year-old daughter, Jozee. Their bodies were found Aug. 22 at their home south of Columbia.

Evidence indicated Allison Abitz, who was an elementary school teacher in Fulton, was strangled and her daughter was drowned in a bathtub, Boone County authorities said Monday.

McLean was Abitz's longtime boyfriend, according to a probable cause statement. The couple was seen together on the night of Aug. 21 and McLean's vehicle was captured on video leaving the home the next day, The Columbia Missourian reported.

It is unclear how McLean is traveling because all vehicles registered to him have been found, Boone County authorities said. Two phones were found burning at a home were he was known to stay, according to the probable cause statement.
