ALAMO — The executive secretary for the city of Alamo was arrested Thursday night for engaging in organized criminal activity after allegedly leaking sensitive police department information to a local drug trafficking organization.

Crystal Denise Garza was formally charged with the third-degree felony Friday and her bond set at $40,000 by Alamo Municipal Court Judge Celia Garza.

A man police identified as her boyfriend, Eddie Ramirez, was also arrested Friday for third degree tampering with physical evidence and will be arraigned Saturday.

Alamo Police Chief Baudelio Castillo said the department became aware of the leak about a month ago, and said compromised information included “very sensitive narcotics information,” such as department procedures, the identities and addresses of undercover officers and police targets — information Garza allegedly gave to local drug dealers.

“We do work very closely with city hall on providing information on our targets, and that information was being leaked out,” Castillo said, noting the police department has “changed (its) way of developing cases.”

The leak jeopardized the safety of his undercover officers, the chief added.

He would not comment on whether the leaked information impacts other local law enforcement agencies.

City Manager Luciano Ozuna Jr., who was Garza’s supervisor, said he, as well as the mayor, city commissioners and city staff, were “stunned” by her arrest and that “it concerns us tremendously.”

Though saying he declined to comment, Ozuna called her arrest “a private matter” which “has nothing to do with the city.”

“When we hire somebody we assume that these are good people … and she was fine, she was doing a great job,” he said. “I don’t know anything about the investigation … I don’t know anything in regards to (her arrest).”

Garza has been employed as executive secretary for approximately four years, he said, and she was suspended without pay Friday. Prior to her work with city administration, she worked for the city’s Economic Development Corporation for six years, he added.

The Alamo Major Crimes Unit’s investigation into the leak remains ongoing with future arrests imminent.

“There are other sources and individuals who will be arrested,” the chief said.

In addition to Garza’s boyfriend, who was arrested at her arraignment, members of her family were present Friday at the city’s municipal court.

She did not have an attorney with her and told the judge she would be hiring one.

If convicted of the third-degree felony charge, Garza faces up to 10 years in prison and a $10,000 fine.
