The man suspected of shooting a Killeen woman to death then killing himself was arrested for threatening a woman with a gun in 2012.

Franklin Rafael Aguilar, 39, of Killeen, was a suspect in the fatal shooting of Christina Yvette McDaniel late Saturday night in Killeen. According to a preliminary autopsy report released Tuesday, McDaniel died of multiple gunshot wounds.

Aguilar, identified in court filings as a staff sergeant in the National Guard, was found in his vehicle Monday in a McDonald’s parking lot in Del Rio, near the Mexican border, suffering from a self-inflicted gunshot wound. He was taken to a hospital, where he died.

Court records obtained by the Herald on Tuesday indicated Aguilar was arrested in April 2012 on a charge of aggravated assault with a deadly weapon. Aguilar’s female victim (not McDaniel) told police he held a gun to her head at point-blank range and pulled the trigger three times.

The weapon did not fire. At the time of his arrest, Aguilar told officers he was exercising “Texas Castle law.”

Aguilar pleaded guilty to the second-degree felony charge in June 2012. He was sentenced to three years deferred adjudication, meaning the conviction would be cleared from his record if he completed the terms of his probation.

In February 2014, Aguilar wrote a letter to Bell County 27th District Court Judge John Gauntt asking to be released from probation early.

According to his letter, Aguilar said his “negative and irresponsible actions” cost him his job as a federal security officer at Fort Hood.

Aguilar added that he continued to work part time as a field artillery instructor with the National Guard, according to the court document.

Re-enlist in army

In his letter, Aguilar said being on probation was keeping him from re-enlisting in the Army, and told Gauntt he had learned from his arrest.

“Sir, this experience have (sic) in many ways changed the way I used to think and act,” Aguilar wrote. “I have learned to think before acting, but most importantly, I have learned to be more mature with myself.”

No order from Gauntt authorizing an early release from probation appeared in the case records, but a summary of facts from Bell County’s probation department stated Aguilar had not violated any of the terms of his probation as of April 2014. Those records showed Aguilar was required to undergo a psychiatric evaluation, as well as evaluations for post-traumatic stress disorder and mild traumatic brain injury. He also completed classes in parenting, life skills and anger management.

While he served his probation, Aguilar may have had access to firearms. Documents stated that Gauntt’s predecessor, Judge Joe Carroll, modified the terms of his parole in October 2012. The change allowed Aguilar to possess, transport or use a gun and ammunition only while “performing active military service” or “while working on a military installation with a government owned weapon.”

Investigation continues

Killeen police are continuing to investigate the circumstances surrounding McDaniel’s murder.

On Tuesday, KPD spokeswoman Carroll Smith said there was no history of violence between the two.

“There was no relationship between the suspect and victim,” Smith said. “She was a friend of his wife.”

McDaniel’s death marked the first homicide in Killeen this year.
