Prosecutors say Charles Glaze faces two counts of manslaughter for causing the accident that killed Michael Brown and Linda Fuggiti.
Glaze's vehicle crossed from the westbound lanes of Highway 99, over the median and into oncoming traffic, striking at least four vehicles on Dec. 12.
"If he had a seizure, as he claimed, he was reckless to be behind the wheel. If he didn't have a seizure he was still, for whatever reason, incredibly reckless, driving the wrong way on a huge thoroughfare like 99," said Sean Teare, Chief of Vehicular Crimes with the Harris County District Attorney's Office.
The crash left twisted metal and shattered glass across all lanes of the Grand Parkway, near Kuykendahl.
Furthermore, prosecutors say he's had previous crashes.
"In fact, he's had a crash before. This one involving numerous cars where he had a seizure and because of that crash, apparently he changed or got a different car, the one that he used in this crash because of additional safety features, meaning he was on notice," Teare said.
Prosecutors also say Glaze was speeding, driving 95 miles an hour.
The Harris County Sheriff's Office said five other people, including Glaze, were taken to the hospital with non-life threatening injuries.

The indictment follows disturbing allegations from 2017 in Montgomery County where Glaze is accused of kidnapping and robbing a woman at a cemetery. Deputies say a woman was visiting her son's grave site when Glaze attacked her at a cemetery in Tomball.
They say he assaulted her with a Taser and showed her a gun before tying her up with zip ties and a necktie.

At the time of the crash, Glaze was wearing an ankle monitor.
Loved ones are remembering the victims killed in the crash.
Michael was known as a true pillar in his community. He was retired and kept an eye on the neighborhood.
"This neighborhood has experienced a great loss with his passing," said Troy Butler, Brown's friend.
Michael, his wife Charlotte, and sister were inside of his HHR during the crash.
Michael died. His wife and sister were rushed to the hospital.
"Charlotte was in the back seat and suffered a broken collarbone," said Butler.
Fuggiti's sister-in-law says Linda was outstanding in every respect. She was in administration for a medical supply company and planned to retire soon.
Her loss and the loss of Michael are felt across the community.
"As the years went on it became more of a family relationship, than just a 'Howdy, neighbor' in passing," said Butler, discussing Brown.
Glaze has been taken into custody by Montgomery County authorities.
