LOUISVILLE, Ky. (WDRB) -- An 11-month-old who was involved in a fatal crash on I-64 earlier this month has died, according to a spokesperson for Kosair Children's Hospital.

Brynlee Summers had been suffering from a broken neck and bleeding on the brain after the accident, which occurred last Thursday. According to Brian Rublein, spokesperson for the hospital, Summers passed away on Wednesday.

The infant is the third life to be claimed by the tragic crash on I-64.

It happened around 9 a.m. in the eastbound lanes near mile marker 106, about a mile from Corydon.

Officials told WDRB's Gilbert Corsey that a Nissan sports car crossed the median from the westbound lanes into oncoming traffic heading east, colliding with a Mercury Mountaineer. The driver of the Nissan, and a 2-year-old passenger in the SVU, died at the scene.

That 2-year-old has been identified as Marissa Summers of Laconia, Ind.

The driver of the Nissan was active-duty Navy, a 23-year-old station in Virginia, the coroner tells us.

The SUV had four people inside -- a grandmother, mother, and her two young children.

The critically injured infant was pulled from the SUV and flown to University Hospital.

"I saw a cloud of snow, and that vehicle was out of control," said Michael Whitehouse, a witness. "It's terrible, just terrible."

Whitehouse narrowly missed the accident, traveling just a few car lengths behind in an 18-wheeler hauling Chevy Malibus from Kansas City to Louisville.

"By the grace of God, I had time to respond," Whitehouse said. "I had time to swerve to the right and keep from striking either of those vehicles, and ended up where I ended up."

Eric Fischer of the Harrison County Police, was one of the first responders.

"What caused the accident was the Nissan was westbound on I-64, near the 106 mile marker, and for an unknown reason, it came across the median into eastbound traffic, impacting with a Mountaineer," Fischer said.

I-64 closed through the morning for investigators to piece together the scene. They appeared to review the car seats, perhaps wondering why the children suffered so much when the impact looks like it's at the front of the SUV, and the adults, who rode up there are OK.

The freeway closed in both directions for parts of the day to reconstruct what happened.

The Corydon community is collecting donations to help the family with funeral and medical expenses.

An account has also been set up at First Harrison Bank.
