‘Stopping his deadly behavior’

The Bexar County Sheriff’s Office was dispatched to a call for a suspicious person just before 6 p.m. on June 23 in the 8400 block of Knapp Rise, which is located in far west Bexar County.

BCSO Deputy Jason Garces, who was the first to arrive on scene, noticed that the original home’s backyard gate was open. According to the affidavit, Garces checked the home’s backyard and found blood on its back porch.

While exiting the backyard, Garces saw Dinh armed with two knives attempting to enter the front of a home across the street, court documents state. Garces also noticed one of Dinh’s hands was bloody.

Garces then called for backup. Two additional BCSO deputies, identified in the affidavit as Steven Calva and Frank Diaz, arrived at the scene at approximately 6:06 p.m.

Garces and Calva, who authorities said positioned themselves in the driveway of a home in the 8400 block of Spitfire Ranch, told Dinh to put down the knives and surrender. According to the affidavit, however, Dinh disregarded their commands.

Dinh then jumped off the porch of the Knapp Rise residence and waved the knives “in a threatening manner” toward Garces and Calva, documents show.

Once again, the deputies told Dinh to stop walking and drop the knives, but he refused. Calva then fired multiple gunshots at Dinh, “stopping his deadly behavior,” the affidavit states.

Diaz then handcuffed Dinh. It is unclear how many times Dinh was struck by gunfire.

Court records show Dinh has a registered residence located next door to the original home law enforcement was dispatched to on June 23.

During a June 23 news conference, Sheriff Javier Salazar described the shooting as “an unfortunate incident” with Dinh “undergoing a mental health crisis.”

Dinh was transported to a local hospital in critical condition, according to the warrant. He underwent surgery for gunshot wounds to his abdomen and lower back area.

A BCSO spokesperson told KSAT on June 30 that Dinh has since been magistrated and transferred to the Bexar County Adult Detention Center.

Salazar also said the three deputies on scene have since been placed on administrative leave.

The deputy who shot Dinh, who was determined to be Calva, is a 16-year veteran with the sheriff’s office. Garces has 2 years of BCSO service while Diaz has been with the sheriff’s office for 10 months.

According to Bexar County court records, Dinh faces a combined $200,000 bond.
