An infant seriously injured in a Saturday night multi-vehicle wreck on I-75 has died, Cobb County police said Tuesday.

Cobb police Sgt. Dana Pierce said traffic had come to a stop on I-75 southbound Saturday night due to construction and lane closures at the Chattahoochee River when, just before 10 p.m., the driver of a tractor-trailer approaching the Windy Hill Road exit "did not brake" and collided with a 2009 GMC Acadia, a 2006 Toyota Highlander and a 2002 Buick LaSabre that were stopped in traffic.

Donald Morgan, 25, and his wife, Candice Morgan, 24, both of Douglasville, were in the Acadia and were taken to Atlanta Medical Center for treatment of "visible injuries," Pierce said. Their six-month-old child was taken to Childrens Healthcare of Atlanta at Scottish Rite in critical condition. The baby died Monday afternoon, Pierce said.

The two occupants of the Buick were also injured, while the two people in the Toyota were not injured.

The driver of the tractor-trailer, Henry Lipps, 59, of New Albany, Ind., was charged with 2nd-degree vehicular homicide and following too closely, both misdemeanors. He turned himself in to Cobb police Monday evening, and has been released from the county jail on $1,300 bond.

Police closed the southbound lanes of I-75 for more than two hours Saturday night and early Sunday to clear the debris and investigate the crash.
