Centerville police continue to investigate Monday night’s wrong-way double fatality on Interstate 675 that killed a 69-year-old Beavercreek man and a 2017 Miamisburg High School graduate.

As authorities seek answers as to why they say Melvin Bonie Jr. drove northbound into southbound highway traffic - causing the wreck that killed himself and 18-year-old Kalip Grimm of Miami Twp. - here are five things we know at this point:

-Test results are incomplete. It is too early to tell if alcohol was a factor in the crash, the Montgomery County Coroner's Office said Wednesday morning. An autopsy has been performed on Bonie, a retired Wright-Patterson Air Force Base analyst. But a cause of death hasn't been determined, according to the county. An autopsy has not been done on Grimm.

-Bonie likely got on the highway from Ohio 48. About 9:20 p.m., the first of four 911 callers said he saw a vehicle go the wrong way on the southbound exit ramp from I-675 from the state route.

-A third person was injured. Police said a 16-year-old female passenger of Grimm's was treated and released from a local hospital. Police would not release her name.

-Lengthy interstate closure. The southbound lanes of I-675 from the Wilmington Pike exit to Ohio 48 were closed for nearly six hours after the crash, according to police.

-Ohio wrong-way fatalities are on pace to decline this year. Including Monday night's wreck, there have been 10 fatalities across the state so far this year, according to the Ohio Department of Transportation. In 2016, 21 fatalities were recorded.
