SAN ANTONIO -

Family and friends of a 29-year old San Antonio man shot and killed by an off-duty Bexar County sheriff’s deputy say they want answers in the case.

It was around 5 a.m. on Aug. 31 on Loop 1604 near Nacogdoches Road that Mat

Jackson was shot and killed after some sort of disagreement with Deputy Anthony Thomas, a 16-year veteran of the department.

Last week, Mat’s brother, Patrick, expressed his frustration about not knowing what happened to Mat on the freeway.

"None of this makes any sense," Jackson said. "I have so many questions about the time frame, how things lined up and just the fact that right now we can't get any answers is very frustrating."

Questions and accusations have also been posted on the Bexar County Sheriff's

Office Facebook page, questioning the county about why no action has been taken against the deputy, who is on administrative leave.

The family has hired attorney Tim Maloney.

"There's a myriad of questions that we have," Maloney said.

Maloney said he wants a thorough investigation and questions whether Bexar County can properly investigate one of its own.

"The difficulty is literally putting one of your own in harm's way, potentially criminally, for many years in prison," Maloney said.

He also hopes to hire famed firearms forensics expert Dr. Vincent Di Maio.

"I've used Vince many times in the past and I plan on using him if he is available in this case," Maloney said.

The Bexar County Sheriff's Department says the investigation into this case is ongoing and that it is not being rushed.

BCSO spokesman Paul Berry said it is important to gather every painstaking detail.
"It will not be done quickly,” Berry said. “It will be done thoroughly and sometimes that takes time."

Berry also said the sheriff's office is fully capable of investigating this case without fear of bias.

"It is not uncommon for a major agency like the Bexar County Sheriff's Office to investigate these types of cases," Berry said.

He also urged anyone in the public to call the sheriff’s office if they have any information on this case.

Once the sheriff's office completes its investigation, the results will be given to the Bexar County District Attorney's office for possible prosecution.
