Police are asking for the public's help in locating three local children who are said to be missing.

According to the Waterbury Police Department, 29-year-old Chrystal McGrath violated the conditions of her supervised visits when she left the McDonald's restaurant located at 530 Reidville Drive with her three children: 2-year-old Maryah Matthew, 5-year-old Dylan McGrath and 7-year-old Maddision McGrath.

A Silver alert for the three siblings has been issued, and police say they believe McGrath is driving either a Honda or Volvo that is reddish or maroon in color.

Chrystal McGrath was last seen wearing a black shirt and black pants/tights and authorities say she may be in the company of her boyfriend, Lester Joy.

If you or anyone you know has any information about the whereabouts of these people, please contact the Waterbury Police Department Detective Bureau 203-574-6941 or 911 immediately.
