Jose Alvarez was angry and sweating, a gun within reach, as he talked to Chicago police officers who had been called to the Little Village neighborhood for a disturbance late last month.

The officers took defensive positions as they spoke to Alvarez through an open window, according to a police report. They finally left when he refused to come to the door and turned off the lights.

Two weeks later, authorities say Alvarez used the gun to kill his wife and 15-year-old daughter and wound his 18-year-old son, who ran to a neighbor’s home for help.

It is not clear why the officers chose not to seize the gun when they were concerned enough that they later filed a “clear and present danger” report about Alvarez, according to records. The police department had no immediate comment.

The case raises other questions about why Alvarez still had his gun on July 3 when he allegedly killed his wife Karina Gonzalez and his daughter Daniela Alvarez.

The day before the officers visited the home, a judge had issued a protection order requiring him to stay away from his family. The order also revoked his FOID card.

But Alvarez was still in the home and still had his gun when the officers arrived on June 22. There’s no indication they even knew about the order yet.

In fact, Cook County sheriff’s deputies didn’t try to serve the protection order until the next day but found no one at home.

That same day, June 23, the Illinois State Police officially revoked Alvarez’s FOID card and informed both the sheriff’s office and Chicago police that his gun should be removed.

The sheriff’s office, facing a backlog of nearly 30,000 outstanding cases, said it had not moved to remove Alvarez’s gun in the days before the shooting.

The Chicago Police Department said it could find no record of any contact from the state police about the status of Alvarez’s FOID card.

As officials were processing the paperwork, the officers answered a call of a “domestic disturbance” at Alvarez's home on June 22. He met the officers at the window of his home.

He complained his wife wanted him to be a “hit man” and mentioned he had a FOID card and a gun. The officers “began to position themselves in a matter for safety” as Alvarez began talking about “multiple subjects not regarding the nature of his call.”

Alvarez gave the officers his FOID card and when they tried to give it back, shut the window,

The officers filed a “clear and present danger” report with state police for “further investigation,” but the state police said they have no record of receiving it.

The next day, the state police would receive word of the protection order and would revoke Alvarez’s FOID card. Under state law, Alvarez was required to hand in his gun.

If he didn’t, Chicago police or the sheriff’s office would be tasked with removing the gun. It’s unclear how long that would have taken.

In Cook County, there are approximately 731,000 FOID card holders. Of those, more than 37,000 have been revoked. Of those revoked, 74%, or roughly 27,000, are non-compliant, meaning they likely to still have their weapons.

“We talk about gun violence and preventing gun violence, and we actually have something that we see, like this, that could have actually been prevented,” said state Rep. La Shawn Ford, who had advocated tightening requirements for FOID cards and increasing funding for enforcement.

“Hopefully, this sounds the alarm louder for the state to put more money into this program,” he said.

It was Alvarez’s increasingly threatening behavior that brought Gonzales to court on June 21 to get the order of protection. She cited his drinking, drug use and threatening behavior.

Gonzalez and her children went to stay with a relative but returned to the home on June 26 after Alvarez agreed to go into rehab, according to prosecutors.

On July 3, Alvarez began accusing his wife of cheating on him, as he had done in the past. Gonzalez told him to stop and joined her children on a couch in the living room, according to prosecutors.

Alvarez’s son told him to “stop or he would call 911” and walked toward his room. Alvarez then rushed past him and grabbed his gun. He shot Gonzalez and Daniela, then returned to the dining room and fired underneath the table where his son was shielding himself with a chair.

Gonzalez was shot eight times and pronounced dead at the scene. Daniela was shot in her face and forearm and died after being taken to Mount Sinai Hospital, police said.

The son was hit in the ankle and ran out of the apartment.

When officers arrived at the scene Alvarez opened the door for them, prosecutors said. The Glock was recovered from the top of his bed with one round in the chamber and more rounds in the magazine, prosecutors said. A second magazine was recovered near the handgun.

Alvarez was charged with first-degree murder, attempted murder and aggravated battery from discharging a firearm. He was ordered held without bond Thursday.
