Police continue to investigate a crash that killed three people in Las Colinas.
The three people killed when a car crashed and sunk into a Las Colinas canal have been identified, authorities said Thursday.
Kenneth Lark, 23, of Austin; his girlfriend, Kaat Debeuckelaer, 21, of Colleyville; and 41-year-old Southlake attorney Ronald Eddins died in the crash.
Eddins, the driver, and Debeuckelaer were pulled from the vehicle Wednesday night after a maintenance worker spotted the four-door Porsche sedan in the canal.
Evidence recovered from the car indicated that a third person was in the vehicle at the time of the crash. Lark's body was found Thursday morning.
Investigators said they believe Eddins lost control of the car while heading west on Northwest Highway and flipped off of the road and into the water near Riverside Drive.
The cause of the crash is under investigation.
Krista Debeuckelaer, Kaat's mother, indicated in a post that her daughter had been missing since Tuesday, when she never returned from an evening out with Lark.
She said the couple had gone to a Dallas Stars game Tuesday evening before being spotted having drinks at about midnight with a lawyer inside the Copeland Bar at the Southlake Hilton.
The couple reportedly met Eddins at the Stars game at the American Airlines Center.
According to Debeuckelaer's post, the bartender said the couple then left, followed by the lawyer.
Investigators know that Eddins, Lark and Kaat Debeuckelaer were also at The Men's Club on Northwest Highway.
Management said the three were at the strip club early Wednesday morning and left together. A manager said Eddins had one drink while they were at the club and did not seem to be impaired when they left.
Donna Berry, a Dallas Area Rapid Transit bus driver, noticed the wreckage as she reported for work just before 5 a.m. Wednesday but thought it was a crash that had already been cleared. Police estimate the crash occurred about two hours before Berry saw the wreckage.
Krista Debeuckelaer told NBC 5 Thursday afternoon that her daughter was a senior biology major at the University of Texas and planned to go to Dental School.
"She was an extremely strong person and beautiful and absolutely amazing," said Brooke Olson, a friend of Kaat Debeuckelaer.
Krista Debeuckelaer said Lark was a recent graduate of the McCombs School of Business at UT.
"He was wise beyond his years, definitely," said Rick Vasquez, a friend of Lark. "He knew how to work hard ... and he knew hard work got you places."
