HOUSTON – The man who was at fault in a crash that killed two people on the Grand Parkway in December has been sentenced to serve 15 years in prison after pleading guilty.

Charles Glaze, 54, was charged with two counts of manslaughter.

Glaze had just left the probation office, was heading westbound on Highway 99 near FM Road 2920 on Dec. 12, 2018, when his red Ford F-150 hit the median and went airborne to the other side of the Grand Parkway, hitting several vehicles and killing two people.

He was wearing an ankle monitoring bracelet when he crashed, and prosecutors said he was driving at 95 mph at the time of the crash.

Glaze told investigators he didn't remember what happened and that he has a history of seizures. He told investigators that a seizure caused him to lose control of his truck.

In 2016, Glaze caused another multi-car crash attributed to a seizure.

Assistant Harris County Attorney Sean Teare said legally, Glaze shouldn't have been driving.

"Every time you renew your license, there's a box you have to check that says, 'I don't suffer from seizures' or 'I have it under control,'" Teare said. "There's a ton of evidence that shows that he didn't. He didn't have it under control."

Michael Brown and Linda Fuggiti were killed in the crash.

Investigators said Fuggiti, 66, was driving a Lexus on the eastbound side of the Grand Parkway when the Ford F-150 went over it, shearing off the top, and crashed into a Chevrolet HHR operated by 73-year-old Brown.

Brown's wife, Charlotte, suffered a broken collarbone.

Four other people were taken to Memorial Hermann Woodlands Hospital.

Glaze's passport was relinquished to authorities.

Court records state Glaze was charged with aggravated kidnapping and aggravated robbery in an unrelated 2017 case in Montgomery County. Montgomery County sheriff's deputies said Glaze's charges are still pending and that Glaze had a $250,000 bond on each charge.

Glaze was not allowed to go to cemeteries, investigators said.

In May, a deadly crash was reported in the same area when a vehicle fell onto the Grand Parkway from the FM 2920 overpass.
