A judge is set to sentence a Colorado woman convicted of attempted murder after cutting a nearly 8-month-old fetus from a stranger's womb.

District Attorney Stan Garnett has said 36-year-old Dynel Lane could spend the rest of her life in prison after a jury convicted her in February of attempting to kill Michelle Wilkins.

Lane was also convicted of assault and unlawful termination of a pregnancy in the 2015 attack.

Prosecutors say they were not able to charge her with murder in the death of the unborn girl because a coroner found no evidence the fetus lived outside the womb.

Prosecutors say Lane was obsessed with having a baby. Her attorneys argued the assault was not a calculated murder attempt, but an impulsive act.
