NEW CITY - The Rockland DA has received the toxicology results from the deadly boat crash on the Hudson River this summer that claimed the life of a bride-to-be and her groom's best man.

Rockland County District Attorney Tom Zugibe says boat operator Jojo John's drug and alcohol test results will not be released until after his case is presented to a grand jury.

John is accused of being drunk behind the wheel of a boat that crashed into a construction barge on the river on July 26.

Bride-to-be Lindsey Stewart, of Piermont, and would-be best man Mark Lennon, of Pearl River, were both killed in the accident.

The district attorney's office says it is still waiting for accident reconstruction results, but expects to present the case by month's end.

John's laywer, David Narain, says his own investigation into the accident points to insufficient lighting on the barge that night.

The U.S. Coast Guard maintains that the barge's lights met federal requirements, although Tappan Zee Constructors, the owner of the barge that the boat crashed into, added more lighting in the days after the crash.
