Three Deaths Cases are Focus of Grand Juries' Attention

Bexar County Grand Juries indicted more than 360 felony cases this week. Three of those indictments related to crimes involving a death.

A grand jury indicted Juan Fragosa for murder. The indictment alleges that on August 31, 2019, Fragosa intentionally caused the death of William Terrell by strangling him with a ligature. Subsequent to indictment, the case is now pending in the 399th District Court.

Gregory Siu was indicted for murder. The indictment alleges that on August 17, 2019, Siu committed or attempted to commit the felony offense of aggravated assault, and while in the course of flight from this offense, he drove a motor vehicle at a speed that was not reasonable under the circumstances into an intersection with vehicles present without stopping, thereby causing the death of Kishana Mitchell. This case has been assigned to the 144th District Court, where it is now pending.

In the third death case, Michael Arriaga Tello was indicted for failing to stop and render aid. The indictment alleges that on July 1, 2019, Tello intentionally and knowingly drove a vehicle that became involved in an accident resulting in the death of Lawrence Nathaniel New and that Tello intentionally and knowingly failed to determine whether a person was involved in the accident and to determine whether that person required aid. This case is currently pending in the 187th District Court.

Because those defendants are all awaiting trial, our office cannot make any further comment on the cases. Each defendants is presumed innocent until proven guilty in a court of law.

Our prosecutors were also very busy in court this week.

In the 226th District Court, Cameron Roby was sentenced to life in prison by District Judge Velia Meza. During the trial, evidence showed Roby was dating the victim, Adrienne (AJ) Dameron, on April 26, 2018, when they were involved in an argument. Roby shot Dameron in the head, killing her. 

The case was prosecuted by Assistant District Attorneys Ryan Groomer and Leslie Cortez.

“This sentence sends the message that domestic violence has no place in our community.  AJ’s life was not one for Cameron Roby to take. We are happy that justice has been served and hope this brings peace and closure to AJ’s family in this violent, senseless crime,” Groomer said.

A jury in the 399th District Court found Charles Robnett guilty of capital murder, resulting in an automatic sentence of life in prison without the possibility of parole. During the trial, evidence showed on Oct. 16, 2017,  Robnett met with the victim, Gary Barnhardt, under the premise of buying marijuana from Barnhardt. Instead, Robnett stole the drugs and opened fire on Barnhardt’s car, killing him. Two other men are charged for their alleged roles in the crime.

The case was prosecuted by Assistant District Attorneys Gretchen Flader and Andrew Fields.

A man who committed his sixth drunken driving offense was sentenced to 40 years in prison on a felony murder charge. During the trial, evidence showed Ricky Cantu was driving under the influence on October 28, 2018, when he struck and killed motorcyclist Rudy Borrego.

The case was prosecuted by Assistant District Attorneys Clint Malloy and Miranda Carrillo.
