All in "Adaumbelle's Quest"

It's been a little over 2 years since my cousin's (Shimon Lesserson) children were kidnapped by my cousin's ex-wife Sarah Lesserson and her convict husband Nick. They took the 4 children (Rivka, Rachel, Yechezkel, Yekusiel) to Mexico. They were last sighted in Sayulita (about 25 miles from Puerto Vallarta). My family and I would love more than anything to have all 4 children reunited with my cousin. Please watch the attached video to help us find them!
