Michelle Roenz Killed: Human teeth and blood found in Humble Home before Tyler Roenz was arrested after Nebraska chase

HUMBLE, TX (KTRK)– A Humble teenager faces charges of unauthorized use of a vehicle as investigators continue to question him after his mother’s body was found in the trunk of his car following a chase in Nebraska.

Tyler Roenz, 17, and his mother, Michelle Roenz, 49, were reported missing from a modest neighborhood late Thursday morning.

New details from prosecution documents highlight the bizarre scene found at the family home.

The video above is from a previous report.

Tyler’s father told Harris County Sheriff’s Deputies Thursday that his wife and son were missing and he could not reach them. He also said her 2011 Mazda 3 was missing from home.

The father reportedly told MPs his son would be allowed to use the car, but only to visit certain locations.

After noticing the missing vehicle, Tyler’s father found a human tooth and blood in the garage, the documents say. He reportedly followed a trail of blood into the home’s master bedroom, where he found at least four other human teeth in a pool of blood.

Investigators reportedly observed other signs of apparent foul play at the home, although it’s unclear what they found.

According to court documents, the father also found his wife’s cell phone and handbag in the apartment. He tried to track his son’s phone using the Life360 app but found that his son had deleted the app and his phone was off.

Surveillance video reportedly showed the Mazda 3 exiting the home at 11:44 a.m

Charges on Michelle’s credit card were pinged in Humble, Texas; Richardson, Texas; Atoka, Oklahoma; and Chetopa, Kansas. The car’s license plate also pinged on a reader near Dallas, documents revealed.

After speaking with the father, investigators issued a CLEAR Alert for both Michelle and Tyler.

Investigators alerted the Nebraska State Patrol after receiving information that the vehicle may have been traveling in the state.

Shortly after the alert, the NSP located the Mazda 3 about two and a half hours west of Omaha and headed west on I-80 near Grand Island, investigators said.

Police officers tried to conduct a traffic stop, but the driver fled.

The chase, which reached speeds of over 110 miles per hour, ended in an accident, investigators said. The Mazda reportedly tried to brake but crashed into the rear of a semi-trailer truck, went off the road and struck a tree in a ditch.

Troopers found Tyler behind the wheel of the car. He was taken to a nearby hospital with non-life-threatening injuries, MPs said. He was still in the hospital when he was last checked.

“The crash occurred near Aurora, Nebraska,” Sheriff Ed Gonzalez said in a tweet. “The male driver has been identified as missing teenager Tyler Roenz. Tyler is being treated at a hospital and is said to be in serious condition.”

Investigators found Michelle’s body in the trunk of the car. Initial reports indicate she died from strangulation and blunt force trauma, HCSO said.

Homicide detectives work with Nebraska authorities to extradite Tyler to Texas. Investigators are urging anyone with information to contact the HCSO Homicide Division at (713) 274-9100.

Described as a passionate animal advocate, mother and wife, Michelle was well regarded, neighbors said.

Tyler was more mysterious. He was charged with attempted sexual assault in early 2022 and was on $10,000 bail, according to court documents. He is accused of assaulting an 18-year-old girl in his car, ripping her shirt off and grabbing her in a school parking lot.

He is not enrolled at Humble ISD where his sister was 2020 Best of Class.

Humble ISD confirmed the teen was a former student in their district.
