Ontario Provincial Police have arrested and charged a man in relation to a fatal collision between a minivan and train last year.

Sisters Wynter Williams, 7, and Brooklyn, 4, were killed in the crash on the morning of June 10, 2012. The collision happened at a crossing on Strong Road just north of County Road 42, outside the town of Lakeshore.

Their brother, Dryden, 5, was critically injured in the crash. The youngest child, Jasmyn, 18 months at the time, suffered only minor injuries in the collision.

Their father, Andrew Williams, of Lakeshore, was also injured.

Williams has been charged with:

  • Two counts of criminal negligence causing death.
  • Two counts of criminal negligence causing bodily harm.
  • Two counts of dangerous operation of a vehicle causing death.
  • Two counts of dangerous operation of a vehicle causing bodily harm.

"It was determined through our investigative unit and all the evidence that we collected and brought forward to the Crown Attorney's office who reviewed the case," OPP spokesperson Sgt. Rick Tonial said of the charges. "They determined ... that there was substantial evidence to lay these charges against this person."

Tonial said officers took their time reviewing the case and evidence. He said the year-long investigation included a 3D reconstruction of the events and several statements from witnesses. After examining all of it, the police presented it to the Crown attorney's office, which, in turn, decided that there was enough evidence for the charges in this case.

"We wanted to make sure that we had all our I's dotted and our T's crossed properly," he said.

Williams was arrested and taken into custody. He will appear in a Windsor court at a later date.

Lawyer Greg Monforton said the family was "very surprised" by the news.

He claims there is not enough known about what happened to lay any criminal charges in the case.

Even though Monforton is representing the mother, Angie Williams, in a civil suit against her husband, Canadian Pacific Railway and the Town of Lakeshore, he said he hopes a coroner's inquest would be called in an effort to "find out who's really to blame here."
