INDEPENDENCE, Mo. -- The second of two women charged with plotting to steal a pregnant teenager's unborn child pleaded guilty to kidnapping and first-degree assault.

Alisa Betts, 18, of Atchison, Kan., entered the guilty pleas Thursday in Jackson County Circuit Court.

As part of a plea agreement, prosecutors dismissed a third charge of felonious restraint.

Betts' co-defendant, Lauren Gash, pleaded guilty in July to kidnapping, assault and felonious restraint. She was sentenced in August to eight years in prison.

Betts was allegedly involved in an attack last year on Amanda Howard, then 18. Prosecutors said the women had met the teen on the Internet and lured her from her home in Clinton, Mo.

They said the two then took the teen to a Blue Springs, Mo., motel, but their plan to take her unborn baby was stopped after Betts got cold feet and called police.

Howard, who has since married, was taking care of her then 11-month-old son in Clinton and was expecting her second child, a girl, when Gash was sentenced in August. Howard did not attend Betts' hearing Thursday, but she is expected to attend Betts' sentencing in November.
