CHESTERFIELD • Authorities have identified a teen killed Tuesday in a three-vehicle crash here as Clayton Pfeiffer, 18, a graduate of St. John Vianney High School and a freshman at Missouri Baptist University, where he played baseball.

Pfeiffer's silver 1998 Honda Accord collided head-on with a black 2012 Infiniti sport utility vehicle about 11 a.m. on Olive Boulevard near Creve Coeur Mill Road.

Chesterfield police Capt. Steve Lewis said the Infiniti, driven by Dale Kawamura, 36, of Oakland, Calif., crossed the center line and struck a white 2007 Dodge pickup and Pfeiffer's car. 

Kawamura and his passenger, Steven Hammer, 33, also of Oakland, were hospitalized for their injuries. The driver of the pickup, Jerome Drapp, 46, of St. Louis, was not hurt.

Kawamura was in satisfactory condition at Mercy Hospital and may be released today, a hospital spokeswoman said.

Police have not said what caused the SUV to cross the center line.

Hammer has been released from a hospital; Kawamura is being treated at Mercy Hospital St. Louis in Creve Coeur. It was not clear Wednesday if Kawamura would face charges.

Pfeiffer was pronounced dead at a hospital.

He was a 2011 graduate of St. John Vianney High School where was the lead-off hitter and second baseman for the school's baseball team. The team finished third in the state in Class 4 last season.

Pfeiffer was a freshman at Missouri Baptist University and played infield on its baseball team. His parents said in an interview that the sport was his biggest passion.

"You'd never see him without a bat in his hands," said his mother, Heather Pfeiffer.

His father, Dan Chinnici, said he believes his son was driving to his apartment in Chesterfield for lunch before going to baseball practice. His father said he was struck about a mile from home.

Chinnici said his only son was a quiet person, a hard worker who enjoyed volunteering with youth baseball teams.

"He was really great with little kids," Chinnici said.

His father said his son wanted to become a teacher and coach baseball if a professional athletic career wasn't possible.

"He was the most dedicated, hardest-working kid I've ever been around," Chinnici said. "He seemed to defy the odds every step of the way."

Eddie Uschold, head coach of MBU's baseball team, said the team gathered Tuesday evening to talk about Pfeiffer's death. He said Pfeiffer was a prospective red-shirt freshman and though he traveled with the Spartans baseball team, he had not played in any of the first six games of the season. He wore No. 4 on his jersey.

Uschold said Pfeiffer's teammates have already bought wristbands to honor his memory and plan to dedicate their season to him.

"He was going to be a good player," Uschold said. "We're hurting, but this is a mature, close-knit group with solid leaders. We want to honor him on and off the field."

Funeral arrangements were still being planned Wednesday, but Chinnici said he expects a service will be held Saturday afternoon at Vianney High School.
