The mother of Etan Patz (AY'-tahn payts) has testified about the "total horror and panic" she felt when the 6-year-old disappeared in 1979.

Julie Patz testified Friday at the New York City trial of Pedro Hernandez.

When she found out her son had never made it to school, her legs started giving out and she had trouble breathing.

Prosecutors say Hernandez hid a brutal secret for more than three decades.

Hernandez's lawyers say the Maple Shade, New Jersey, man is mentally ill and imagined he killed the first-grader, whose body was never found.

Hernandez's first trial ended in a jury deadlock.

Etan was among the first missing children featured on a milk carton. The May 25 anniversary of his disappearance became National Missing Children's Day.
