Update at 3:20 p.m. Tuesday: Revised to include a statement from the Grambling State University president.

The 5-year-old daughter of two college professors was found unharmed at the scene of a suspected murder-suicide in Rockwall where a fire was extinguished Monday morning.

Emergency workers discovered the bodies of the girl's parents, Hyun Seop "Harry" Lee and Yoon "Debbie" Kim, inside their home in the 1200 block of White Water Lane at about 5 a.m.

Rockwall police said they suspect Lee fatally shot his wife, started the fire to cover it up and then killed himself.

The couple's daughter was found asleep in a car parked on the driveway.

It's unclear whether a parent put the girl in the car or whether she got there on her own, said Sgt. Aaron McGrew with the Rockwall Police Department.

McGrew confirmed that police are investigating a Facebook post that appeared on Lee's account early Monday that was visible to his friends on the site.

The post, written in Korean, seems to be a suicide note and a list of grievances written by Lee about his wife. He complained that Kim had been "a disrespectful wife" and that she hadn't treated his parents well.

"I'm so sick and tired of her making important life decisions without talking with me," he wrote. "All my suggestions are ignored. She always did it in her favor. "

Lee went on, saying his wife had accused him of being paranoid that she was cheating on him. He said he felt he was not a priority to Kim.

"I will face my death with a smile," he wrote. "Goodbye."

Lee, 42, had pursued a doctoral degree in engineering at Georgia Institute of Technology, according to his LinkedIn page. He also listed bachelor's and master's degrees from Hanyang University in Seoul, South Korea.

He was an assistant professor in Grambling State University's industrial and engineering technology program for almost two years before he died.

Kim, 39, was an assistant professor of engineering at Texas A&M University-Commerce, where she had worked for three years. She also studied engineering at Hanyang University and was a postdoctoral fellow at Georgia Tech, according to her LinkedIn page.

Noah Nelson, an A&M-Commerce spokesman, said Kim's boss — Brent Donham, dean of the College of Science and Engineering — had called her "one of my stars."

Nelson described Kim as an academic who was well-liked by students and peers.

"It was rare for a woman to be in the field of construction engineering," Nelson said. "That also made her special."

Her husband taught at the university for one semester in 2016.

A&M-Commerce president Ray Keck and Grambling State president Richard Gallot, Jr. issued statements to students Monday reminding them to seek help from the counseling center if they need support.

"This tragedy knocks us to our knees, an occurrence more appropriate to the Greek classics than to Rockwall-Commerce," Keck wrote in his statement. "I hope their daughter's grandparents or extended family can arrive very soon."

In his statement, Gallot offered condolences to Lee's family and anyone else who knew the couple.

Julee Walker, a flute professor at A&M-Commerce, met Kim through a group of Korean professors who would meet up for lunch. Walker said she was just starting to get to know Kim.

The two were close in age and had been meeting for dinner occasionally. They had plans to have lunch together Wednesday.

Walker said she was stunned when she read Keck's email saying Kim and her husband were found dead.

"Total shock," Walker said. "And on top of that, they both — you can tell they really love their daughter."

Walker said Kim was bubbly, friendly and outgoing. She described Lee as "very quiet but very nice." She remembered the couple as devoted parents.

Their Facebook profiles and Instagram pages were filled with family photos and comments from people saying how beautiful they looked and how quickly their daughter was growing up.

Lee and Kim bought their home on White Water Lane in March 2016, according to property records. Rockwall police said they had not been called to their address before Monday.

Aaron Bray, who lives across the street, said he woke up to the sounds of diesel engines and lights from firetrucks in the neighborhood near John King Boulevard and Quail Run Road.

When he walked outside, flames were shooting from his neighbors' home. A hole was burned through the roof, and debris lined the steps to the front door.

Kim and Lee's daughter has played with Bray's sons from time to time. He said he talked to police and offered to help care for the girl, but they told him relatives were traveling from South Korea to look after her.

"The wife and daughter always seemed cheerful," Bray said. He said Lee was rarely in town because of his out-of-state job.

A group of A&M-Commerce engineering students whom Kim taught set up a GoFundMe campaign to gather donations for her daughter. One of the students, Philip Dattilo, said she was one of the "kindest and most caring professors" he had.

The deaths of Lee and Kim follow another apparent murder-suicide in neighboring Rowlett, where police say a man fatally shot his 11-year-old son Saturday night before killing himself.

Policarpo Gonzalez-Flores had been arguing with his wife, the boy's stepmother. She told police that he called her to say that he had shot his son. Then she heard a gunshot, and the call ended.

James Gonzalez was an honor student at Coyle Middle School, where he was in the sixth grade.

His mother divorced Gonzalez-Flores in 2012, but the two appeared to have had a cordial split, court documents show. There were no allegations of domestic violence or requests for a protective order, and the woman demanded less child support than the state recommended.

"Policarpo Gonzalez has custody of child 80% of the time and already pays for any and all expenses," the final decree of divorce reads.
