ROSELAWN, Ind. (AP) – State police say southbound Interstate 65 in rural northwestern Indiana is open again after a man and two of his children died when their vehicle rear-ended a semitrailer in traffic backed up after a tanker carrying nitric acid rolled over. 

Sgt. Tony Slocum says the southbound lanes reopened Tuesday morning, about 12 hours after the tanker crash near Roselawn, about 30 miles south of Gary. Slocum didn't have an estimate of when the northbound lanes might reopen, saying crews were trying to get the tanker upright without spilling more nitric acid.

A coroner says the father and two children who died were from Jasper County, but he didn't immediately release their names.
