STONY BROOK - Police are investigating a missing person's case involving a mother who allegedly abducted her child instead of turning him over to Suffolk County Child Protective Services.

Kristin Kapp was ordered to turn over her son Sebastian Parsons-Kapp to CPS, police say. When Kapp ignored the order, a warrant for child neglect was issued on April 27.

The child's father, who previously had an order of protection that prohibited contact with the child, reported him missing on June 9.

Kapp and her son, 5, were living in Stony Brook. They are believed to be in New York, possibly in the city.

Anyone with information about this incident or where the pair is located is asked to contact 911 or Sixth Squad detectives at 631-854-8652.
