A San Diego housewife and an Arizona Border Patrol agent were both killed in recent separate incidents involving drug law enforcement. Housewife Valeria Tachiquin-Alvarado and Border Patrol agent Nicholas Ivie become the 48^th and 49^th persons to die in US domestic drug law enforcement operations so far this year.

[image:1 align:right]Tachiquin-Alvarado, a 32-year-old mother of five and a US citizen, was shot and killed September 31 by an as yet unidentified Border Patrol agent as she attempted to leave the scene of a raid, according to Chula Vista police, who are investigating the killing. She was on probation for a 2011 drug conviction at the time.

The fatal encounter began when a group of plain clothes Border Patrol agents went to an apartment to arrest a previously deported felon at an apartment where there had been prior complaints of drug activity. Tachiquin-Alvarado answered the door, was questioned and released, then walked to her car nearby.

Other Border Patrol agents then "contacted" her as she prepared to drive away. She then allegedly pulled away from the curb, striking one of the agents. The agents then told her she was under arrest for vehicular assault and tried to grab her car keys from the ignition. But Tachiquin-Alvarado instead pulled away, striking the first agent again and leaving him perched on the hood of her car.

She drove off at speeds of around 25 mph as the agent yelled at her to stop the car. After driving about 200 yards, Tachiquin-Alvarado began to make a turn, and the agent on her hood drew his gun and fired repeatedly into the windshield, killing her.

Police said they have witnesses to confirm their version, but other witnesses gave a different account.

"I just witnessed the officer walking toward the female's car. She was backing up and then he discharged, his weapon started firing," said Prince Watson, a witness.

Chula Vista police are continuing to investigate and will forward the results to the District Attorney's Office for a ruling on whether the shooting was justified. But Tachiquin-Alvarado's family is not waiting for the investigation to be completed. They held a tearful news conference and candlelight vigil near the scene of the shooting last Monday, and a family attorney has vowed that a civil suit will be filed.

Oh, and the guy the Border Patrol was looking for? They didn't find him.

Then, in the pre-dawn hours last Tuesday, Border Patrol Agent Ivie was shot and killed and a second agent wounded in what federal investigators are now calling a friendly fire incident. According to the FBI, which is investigating the case, Ivie and other agents responded to a tripped sensor that indicated movement in a remote border area "described as a drug-trafficking corridor used by the Sinaloa cartel to smuggle marijuana and other drugs into the US."

Three agents approached the area of the tripped sensor from different directions, perhaps without knowing the others were so close, lost radio contact with each other, then "Ivie got spooked and started to shoot" and "another agent shot back and those bullets killed Ivie," according to an Arizona law enforcement source.

The FBI would only go as far saying there were "strong preliminary indications" that Ivie's death and the wounding of the other agent were "the result of an accidental shooting involving only the agents."

But Arizona law enforcement sources said there was no evidence of illegal border crossers in the area, that the motion sensors sometimes give false indications, and that shell casings on the scene suggested a "blue on blue, friendly-fire event."
