A Pennsylvania prosecutor says a couple charged with letting their daughter's teeth rot so badly that her life was endangered won't face charges in the deaths of three other children.

Northampton County District Attorney John Morganelli said Monday there's not enough evidence to charge Kenneth Wanamaker Jr. and Jessica Hoffman in connection with two stillbirths and a 7-month-old son's pneumonia death.

The Morning Call newspaper (http://bit.ly/1JSDp0m ) reports that investigators were looking at whether Hoffman's methamphetamine use while pregnant contributed to Tyson Cole Wanamaker's November 2011 death and a December 2013 stillbirth.

Pennsylvania law protects pregnant women from facing charges connected to how they treat their fetuses.

Wanamaker is trying to rescind his guilty plea to reckless endangerment and false swearing charges in the teeth case. Hoffman faces trial Sept. 28 on a child endangerment charge.
