ST. PAUL, Minn. -- One year after a vehicle struck and killed a woman who was crawling on Interstate 35E in St. Paul, authorities still haven't found the hit-and-run driver and still aren't sure why she was on the freeway.
State Patrol spokeswoman Lt. Tiffani Nielson says authorities would reopen the investigation into the death of 28-year-old Emily Boone if credible leads surface.
Nielson tells the St. Paul Pioneer Press that investigators don't know if Boone intentionally slid down a wall to the freeway on the night of Jan. 2, 2015, or if she fell onto the roadway accidentally.
The Patrol says an autopsy put Boone's blood-alcohol level at 0.35 percent, more than four times the legal limit for driving, and she had mentioned contemplating suicide to relatives earlier that night.
