Eastern student Lauren Leffler was left brain dead after a 23-year-old woman hit Leffler—accompanied by a male—after running a red light on Sunday in Bloomington, according to Bloomington authorities.

Leffler, 21, and Nicholas Jefferson, the male friend of Leffler, were crossing the street when they were allegedly hit by Katie Lawson, who later fled the scene.

Leffler and Jefferson were both taken to Advocate BroMen Medical Center—Leffler was pronounced brain dead at 1:25 p.m. on Sunday while Jefferson released shortly after.

Lawson, who was arrested at 9 a.m. on Sunday, could be charged with aggravated driving under the influence in an accident that caused injury or death, failure to report an accident with injury, driving on a suspended license, failure to reduce speed and driving an uninsured vehicle.

Lawson is a resident of Bloomington.

At a court hearing on Monday, Lawson’s bond was set at $250,000 by Associate Judge Bill Yoder. Her arraignment is set for July 6.

“The coroner doesn’t usually rule causes of death right away with (circumstances) like this,” Bloomington Police Sgt. Brad Ficek said.

Ficek was not called to the scene at the time of the accident.

McLean County Coroner Beth Kimmerling said Leffler’s autopsy in scheduled for today after organ procurement.

“Lauren survived her injuries long enough to make it to the hospital, but at the hospital she (had) been declared brain dead,” Kimmerling said. “She is being kept alive on life support because her family believed she wished to donate her organs.”

Leffler is a member of Alpha Gamma Delta sorority.

Leffler was supposed to graduate on Dec. 15, 2012 with a bachelor’s in family and consumer science major concentrating in dietetics.
