A former George Ranch High School student has pleaded guilty to murdering a fellow classmate in August of 2019 and has been sentenced to 36 years in prison.

Dylan Robert Rosilez, who was 16 at the time of the Aug. 22 shooting, faced life in prison if convicted of the first-degree offense of murder.

Rosilez, who was in 11th grade at the time of the killing, is accused of shooting Matthias Konrad, 16, who was also a junior at GRHS, according to the Fort Bend County Sheriff’s Office.

Rosilez was arrested at his home later in the day after an anonymous tip was made to Crime Stoppers.

The shooting took place around 1:30 p.m. at Savannah Moss Park, located on Savannah Moss Drive in the Tara subdivision. Residents called 911 after hearing gunfire. Konrad’s body was found in the park by friends.

He had wounds to the face and torso and was alive when law enforcement arrived.

A helicopter transported Konrad to a Houston hospital where he died.

Prosecutors believe Rosilez, who went by the nickname “Groove,” shot Konrad during a robbery at the park.

According to sheriff’s deputies, Rosilez was known to sell illegal drugs at the community park. One acquaintance told investigators that Rosilez had called her and laughed about shooting Konrad.

Investigators said Rosilez posted Snapchat videos of the helicopter taking Konrad to the hospital, a black revolver, the court-ordered electronic ankle monitor he had cut off his ankle, and Fort Bend County sheriff’s deputies walking and driving through the neighborhood as they searched for the shooter.

Apparently, Rosilez had removed the monitor so he couldn’t be tracked by authorities when he met with Konrad in the park.

Rosilez told deputies he replaced the monitor on his ankle using duct tape. Although he was 16 at the time of the shooting, Rosilez was tried as an adult.

Tameika Carter, 400th Judicial District judge, accepted the plea bargain agreement between Rosilez and prosecutors on April 27 and immediately sentenced Rosilez to prison with credit for the 614 days he has already served in county jail while awaiting trial.

Because a deadly weapon was used in the offense, Rosilez has to serve at least half of his sentence before being considered for parole.

Rosilez was represented by Shawn McDonald. Tyra McCollum presented state’s evidence.
