Lakeville police said Monday they're trying to figure out why a teenage driver's pickup truck crossed a center line and smashed head-on into a sedan, killing members of three generations of a Lakeville-area family.
Police said they are checking into several factors that may have caused the accident, including whether the teen could have been texting or talking on a cell phone.
"We're still digging into that," Detective Sgt. Andy Bohlen said. "Anything's possible. We certainly don't know at this point what caused it, but we want to find out for all those involved. We want to try to see if we can narrow down what caused this tragedy."
Police said they could not release the teen's name because of the potential for charges against the juvenile.
There's nothing to indicate that alcohol and drugs were a factor, but nothing has been ruled out, Bohlen said.
"We just really want to find out why this happened," he said.
The 17-year-old youth is from tiny Dundas in rural Rice County.
The teen was driving after dark without headlights when he caused the accident that killed a Lakeville woman, her daughter and also a granddaughter, police said.
