GLENWOOD  (AP) — Charges say the man accused of driving drunk and killing a Minnesota coach's son had a blood-alcohol content more than four times the legal limit.

Thirty-eight-year-old Dana Schoen of Starbuck faces three criminal vehicular homicide or operation charges.

The complaint says a breath test showed Schoen had a blood-alcohol content of 0.351 percent. Minnesota's legal limit is 0.08 percent.

Schoen's pickup collided head-on Saturday with a sport utility vehicle carrying Southwest State University men's basketball coach Brad Bigler.

Bigler's 5-month-old son, Drake, was killed. Bigler was critically injured. His wife, Heather, who was driving the SUV, and her 74-year-old grandmother, Sharon Schuler of Granite Falls, also were hurt.

Bigler's surgeon says Bigler is making good progress and that Schuler also is doing well.
