Diane Schuler's brother, whose three daughters were killed in the fatal July 26 collision on the Taconic, says he never would have expected his sister could've been drinking and doing drugs that day.

"We would never knowingly allow our daughters to travel with someone who might jeopardize their safety," said Warren Hance and his wife Jackie through a family spokesperson after Schuler's toxicology results were released.

Police say Schuler, 36, had a blood-alcohol level of more than twice the legal limit and had smoked marijuana as recently as 15 minutes before the crash.

The collision killed Schuler, her 2-year-old daughter, three nieces and three Yonkers men she slammed into head-on.
