Authorities say they found a baby boy dead in a freezer at a South Florida home following his mother's suicide threats.

The Miami Herald (http://goo.gl/V5nujw ) reports that 37-year-old Paola Vargas-Ortiz remained under mental evaluation at a Miami hospital Wednesday.

Authorities say Vargas-Ortiz was poised to jump from the Seven Mile Bridge in the Keys Sunday afternoon when she told them that she had tossed her 4-month-old son in first. Wildlife officials and the U.S. Coast Guard conducted a brief search before she changed her story.

After Monroe County deputies took Vargas-Ortiz into custody, officials say she told them the child was actually dead in a freezer. Homestead police went to the woman's home and confirmed that the child's body was there.

Medical examiners will determine a cause of death. No charges have been filed.
