Authorities say that the children, who are cousins, were at another relative's house for a weekend visit when they were assaulted. Authorities are searching for Leonard Chopin, 24, who once resided on Jasper Lane in LaPlace, and is believed to be in the Kenner area. According to Sheriff's Office spokesman Capt.
