ST. JOSEPH, Mich. (AP) — No charges will be filed in a September crash that killed two children after a driver stopped to dislodge a bucket that was stuck under her car on the U.S. 31 bypass in southwestern Michigan.

In a statement Wednesday, Berrien County prosecutor Michael Sepic says there might be “equal fault in this tragedy.” But he’s declining to file charges against 22-year-old Tanjela Williams of Benton Harbor or 16-year-old Alayna Rishaug of New Carlisle, Indiana.

Rishaug didn’t stop in time to avoid a rear-end crash with Williams’ car on Sept. 16. Sepic says Williams came to a complete stop on the highway instead of using the shoulder.

Two of four children in Williams’ car were killed. Nearly three months later, Williams still is in a hospital.
