DANBURY — State police and local officials would not release any more details Monday about a police shooting that left one man dead and a woman injured over the weekend.

A Danbury officer shot and killed a man who charged at the officer with a knife during an incident Saturday night at the Glen Apartments, a senior housing complex near Rogers Park, according to an initial state police report.

A woman living in the apartment, who is related to the man, also was injured during the incident. Officials would not comment on her health Monday.

The shooting is the first involving a Danbury police officer in at least 20 years.

Several shooting incidents involving police around the state over the past two years, and repeated high profile controversies across the country, have cast a national spotlight on how often — and who — officers shoot.

Both state and local police remained tight-lipped about the exact circumstances surrounding the shooting Monday, citing an ongoing investigation into the officer’s use of force.

State police routinely wait several days or more than a week to identify the victims or officers involved in a police shooting.

Police officers responded to the apartments on Memorial Drive in Danbury around 9:30 p.m. for a report of suspicious man.

After a “brief confrontation,” the officer tried to use a Taser but it was “ineffective.” When the man charged while holding a knife, the officer fired multiple rounds and hit the man at least once, according to the initial police report.

The woman was injured when the shots were fired, but Mayor Mark Boughton said earlier she was expected to be OK. Boughton and hospital officials declined to comment on the woman’s medical condition Monday.

“Out of respect to her family and next of kin, I just can’t release any more about that,” Boughton said.

Boughton and police would not confirm the identity of either the woman or the man, although law enforcement sources suggested the man was known to officers and has an extensive record with the law.

Attempts to reach the woman and man’s family members were unsuccessful Monday.

Officials also would not identify the officer involved.

The Connecticut State Police Western District Major Crime Squad is investigating at the request of the state’s attorney’s office, which will determine whether the shooting was justified.

Boughton and law enforcement sources argued prosecutors will confirm the officer fired in self defense.

Danbury Police policies require a minimum 72 administrative leave for an officer involved in a shooting to evaluate the incident and the officers physical and mental health after the incident, Chief Patrick Ridenhour said. After that period ends, administrators and the officer decide together whether the officer should turn to duty or stay on leave.

Depending on the results of the state attorney’s review, the department could conduct an internal investigation to determine whether any department policies were broken, Ridenhour said. Local training officers also will examine the circumstances of the incident to decide if there are any lessons to incorporate into officer training.

“You always want to take a look at any type of force, whether its a taser or physical force or, unfortunately in this case, lethal force to see if there are any training issues we need to address,” Ridenhour said.

The state attorney’s office investigations typically take months to complete and details about police shooting incidents are often withheld until the conclusion of that report.

The state attorney’s office took more than a year to conclude in a report, released two weeks ago, that a New Milford police officer was justified when he fatally shot a man during a brief standoff in August 2017.

In that case, state police waited a week to identify the victim and officer involved in that shooting.

Prosecutors also took more than nine months to conclude in January 2018 that a Bridgeport police officer was justified when he shot and killed 15-year-old Jayson Negron in early May 2017.

That incident led to emotional protests throughout 2017, with activists decrying the investigation, its duration and ultimately its conclusions.

Danbury police are expected to compose their report on Saturday night’s incident after the holiday this week. State police would not give a time frame on when investigators would release more information.
