Kansas City, Mo. ? One of the nation’s leading death penalty lawyers is seeking to represent the Kansas woman accused of cutting a Missouri woman’s baby from her womb and claiming the infant as her own.

Judy Clarke, who helped Unabomber Theodore Kaczynski and bomber Eric Rudolph avoid the death penalty, filed paperwork Thursday in federal court seeking to join Lisa Montgomery’s defense team.

Prosecutors have said they plan to seek the death penalty against Montgomery, who is charged with kidnapping resulting in death.

She is accused of killing 23-year-old Bobbie Jo Stinnett, who was eight months pregnant with her first child, on Dec. 16, then cutting her open with a kitchen knife and stealing her baby. Prosecutors have said Montgomery showed the baby off as her own in Melvern, Kan., before her arrest.

Her trial is set for April.
