A Niles woman who accidentally drove her vehicle into a van on U.S. 12, killing four people — including a one-year-old boy — will spend three months in jail.

Cecilia Cheney, 44, was sentenced Thursday to 90 days in jail by Cass County District Court Judge Stacey Rentfrow.

Cheney pleaded no contest earlier this year to four counts of moving violation causing death, all stemming from a fiery two-vehicle accident that occurred on U.S. 12 east of Bell Road in Niles on Oct. 9, 2011.

Cheney’s vehicle crossed the centerline and hit a van head-on coming from the opposite direction. The passengers in the van — Devin Stone, 1; Curtis Stone, 50; Stacey Garza, 35 and Kathleen Marks, 57 — all died. All were from the South Bend area.

Prosecutor Victor Fitz said Thursday Cheney didn’t mean to kill any of the victims, but did when she carelessly took her eyes off the road to get something out of her purse in the passenger’s seat.

“She is not evil, but she killed,” Fitz said.

Fitz said Cheney was speeding as fast as 67 miles per hour in a 55 miles-per-hour zone.
