NEWTOWN, Conn. (AP) — A funeral for one of the Connecticut school shooting victims, 6-year-old Noah Pozner, is being planned for Monday.

Pozner’s uncle, Alexis Haller, says the funeral is scheduled for 1 p.m. at the Abraham L. Green and Son Funeral Home in Fairfield, Conn.

Haller describes Noah as “smart as a whip,” gentle but with a rambunctious streak.

Noah had a twin sister, Arielle, who was assigned to a different classroom and survived Friday’s rampage in which 20 children were killed. Noah had called Arielle his best friend, and with their 8-year-old sister, Sophia, they were inseparable.
