SAN ANTONIO -- A 35-year-old man died in police custody Friday morning shortly after a Taser gun was used on him.

Officers responded to a domestic disturbance call at 4:30 a.m. in the 1100 block of Brunswick following multiple calls from the man's wife, police said.

When police arrived at the residence, Sergio Galvan was acting irrational and aggressive toward officers Richard Smith, a 17-year veteran, and Richard Garcia, an eight-year veteran, said Assistant Police Chief David Head.

One of the officers then used pepper spray on Galvan, which the officer reported was ineffective, Head said.

The other officer then used his Taser gun, stunning Galvan three times, Head said.

"The second officer deployed the use of a Taser, in what's called a drive-stun mode, which is not fired using the probes, but was in close contact with the individual," Head said. "Again, the officer described the use of that weapon as ineffective."

The officers then handcuffed Galvan, who police said had been drinking, and realized he was unresponsive, said Lt. Richard Martinez of the San Antonio Police Department.

Officers then began using CPR on Galvan until an ambulance arrived, but Galvan never responded.

Galvan's wife, Cindy Galvan, disputes what police said happened.

She told KSAT 12 News that her husband had received a mysterious and threatening phone call prior to her calling 911.

She said that instead of helping her husband, police officers killed him.

"They Tasered him and gave him a heart attackcomma is what they did," Cindy Galvan said.

Cindy Galvan also said that police officers were insensitive over her husband's death.

"I said, 'Where is my husband?'" Galvan said. "They just smirked at me."

Cindy Galvan added that her husband drank two beers before he died and she believes that his chronic high blood pressure and cholesterol may have contributed to his death.

The Bexar County Medical Examiner's Office said preliminary autopsy results will be released Friday afternoon and toxicology results will take several weeks.

Smith and Garcia will remain on duty while the death is investigated.

SAPD began using Taser guns in December 2006 and since then officers have deployed them 28 times. Friday's incident was the first death in San Antonio related to a Taser gun.

For the time being, SAPD does not plan to change its Taser gun policy.
