The family of missing Connecticut mom Jennifer Dulos marked her 51st birthday Friday with a special request.

“We miss her more than words can say. In Jennifer’s honor, her family and loved ones would like to encourage gestures of kindness — send a loving note to a friend, assist a person in need, tell a child they’re special,” the family said in a statement.

The New Canaan mom of five has been missing since May 24.

Her estranged husband, Fotis Dulos, and his girlfriend, Michelle Troconis, have been arrested for allegedly tampering with evidence and hindering prosecution in the case.

Authorities are treating the case as a homicide.
