Juvenile who killed fellow student will stand trial as an adult in Fort Bend County

Mathias Konrad was killed on Aug. 22 , 2019.
A teenager who shot and killed a fellow George Ranch High School student near Greatwood and Tara subdivision last August will stand trial as an adult on murder charges.

Dylan Rosilez, 16, was certified to stand trial as an adult on Sept. 3, for the alleged murder of Mathias Konrad.

The certification hearing was held in County Court at Law No. 4 Judge Toni M. Wallace.

A certification hearing is the legal process for removing a juvenile from the juvenile justice system in order to prosecute him as an adult.

In order to certify a juvenile to stand trial as an adult, a juvenile court must find there was probable cause that the crime was committed, and that because of the seriousness of the offense alleged or the background of the child, the welfare of the community requires criminal proceedings and warrant his removal to the adult criminal justice system.

Once certified as an adult, a juvenile is entitled to bond and a trial by jury. All defendants are presumed innocent until proven guilty.

Murder is a first-degree felony punishable from 5 to 99 years or life in prison and a fine up to $10,000. Rosilez was bound over to district court on a $75,000 bond.

“Typically, we prosecute juvenile offenders under the provisions of the Texas Juvenile Justice Code. The Juvenile Justice Code requires law enforcement to evaluate juvenile offenders and utilize a myriad of resources and services to rehabilitate juvenile offenders,” said District Attorney Brian Middleton.

“But sometimes the circumstances are so severe that the juvenile system cannot appropriately address the crime, the offender, and public safety. In those cases, we are obligated to seek redress under the adult criminal justice system.”

Chief Juvenile Prosecutor Tyra McCollum and Assistant District Attorney Johnny Wen prosecuted the case.

Attorneys Shawn McDonald and Sheila Burnett represented Rosilez.

Konrad was killed at a park on Savannah Moss Drive in Richmond on Aug. 22, 2019.

About to start his junior year at the high school in Lamar CISD, Konrad was described as “a bright, athletic, vibrant young man, who loved music and spending time with his friends.”

Soon after the shooting, a girl told the police that the Rosilez told her that he killed Konrad. She said the shooter called her seconds after shooting Konrad.

“He said to me that, ‘I was about to rob Matthias, but he started fighting me back,'” she said. “Then, he grabbed a gun and shot him in the face, in his chest and in his back.”

She called 911 and led officers to the suspect’s home a block away, where they arrested him.

Investigators said the suspect was on Snapchat, showing the medical helicopter flying the victim to the hospital, a gun and what appeared to be a cut-off ankle monitor, suggesting that Rosilez had already been charged with some crime as a juvenile.
