A 10-year-old boy died Tuesday from injuries in a Jessamine County collision Sunday. He was the fourth person involved in the accident to die.
Michael Osland died of multiple blunt-force trauma at University of Kentucky Chandler Hospital, according to a news release by the Fayette County Coroner's Office.
Michael Osland's sister Lauren, who was 5, died Monday from her injuries.
The drivers of the two cars involved in the crash died at the scene, Nicholasville police officer Kevin Grimes said.
Robbie Chaffins, 51, of Clay City, was driving a maroon SUV that crossed the center line of U.S. 27 near Carpenter's Dish Barn about 1 p.m. Sunday, Grimes said.
The SUV collided head-on with a Ford pickup driven by Rusty Johnson, 28, of Lexington.
Michael and Lauren Osland were in the truck with Johnson, who was engaged to their mother, Rachel Osland, 33.
Rachel Osland also was in the pickup and was taken to UK Hospital in serious condition.
It was not clear Tuesday afternoon whether speed or alcohol were factors in the crash. The investigation is continuing, according to Nicholasville police.
Both Lauren and Michael Osland attended Julius Marks Elementary School in Lexington.
Principal Lynn Poe remembered both of them as good students.
"Lauren was just a precious, beautiful student," Poe said. "She had a beautiful smile."
Michael Osland led the school's robotics team last year, Poe said.
Teachers at the elementary school called every student's parents before school Tuesday to let them know what happened over the weekend, Poe said.
Lisa Deffendall, spokeswoman for Fayette County Public Schools, said a letter was sent home to the parents of fifth-graders at the school notifying them of Michael's death. Grief counselors were at the school working with Lauren's and Michael's classmates Tuesday. Counselors will be at the school Wednesday to help students deal with the deaths, she said.
