The mayor of Gloucester, Massachusetts says there is no evidence a group of girls at the city's high school made a pact to become pregnant.

After a closed-door meeting with city, school and health leaders, Mayor Carolyn Kirk said there was no independent confirmation of any plan among the teens to get pregnant and raise their babies together.

The principal who first told Time magazine of such a pact was not invited to the meeting.

Kirk says Joseph Sullivan is now "foggy in his memory" as to how he first heard the information.

This year, 17 girls have become pregnant, four times the typical number of Gloucester High students who become pregnant.
