Cynthia Nixon Speaks Out After Fatal Shooting of Jonathan Joss: 'We Will Not Let This Stand'

Cynthia Nixon is mourning the loss of Jonathan Joss and calling for answers after the actor was allegedly shot and killed in San Antonio on Sunday, June 1.

In a post shared to Instagram on Tuesday, June 3, the Sex and the City actress, 59, said she was “devastated” to learn that Joss, whom she described as a “wonderfully talented actor and musician,” was fatally shot on Sunday, June 1.

She added that she and her family were big fans of Parks and Recreation. Joss, also 59, had a recurring role as Chief Ken Hotate on the sitcom.

“He and his husband had been repeatedly harassed and worse by homophobic neighbors who recently burned their house to the ground,” Nixon’s post continued.

Hours after the news broke on Sunday, his spouse, Tristan Kern de Gonzales, took to Joss’ Facebook page to reveal that he was present when Joss was shot, and claimed the issue was rooted in homophobia. 

“The men were collecting mail at their old address when a former neighbor came at them shouting homophobic hate and shot Jonathan to death,” the Gilded Age actress wrote.

Nixon said Joss died protecting the person he loved: “His husband says he would also have been shot had Jonathan not pushed him out of the way.”

She ended her post calling out local authorities.

“The San Antonio police force is saying there is “no evidence” that this was a hate crime,” Nixon wrote. “We will not let this stand.”

PEOPLE did not immediately receive a response from the San Antonio Police Department. 

In a statement shared to the SAPD’s Facebook account on Monday, June 2, the department said there was “no evidence” to support the theory of Joss’ death being the result of a hate crime. 

“SAPD Homicide is currently investigating the murder of Mr. Jonathan Joss. Despite online claims of this being a hate crime, currently the investigation has found no evidence to indicate that the Mr. Joss’s murder was related to his sexual orientation. SAPD investigators handle these allegations very seriously and have thoroughly reviewed all available information. Should any new evidence come to light, the suspect will be charged accordingly,” their statement read. 

Sigfredo Alvarez Cejam, 56, who fled the scene in a vehicle, was later detained by police and named as a suspect. He was subsequently booked for murder, and the investigation is still ongoing, per police. 

A police report obtained by PEOPLE on Tuesday, June 3, details that Ceja admitted that he “intentionally and knowingly discharged a weapon” at Joss.

According to Kern de Gonzales, before Joss was killed, their former home was “burned down after over two years of threats from people in the area who repeatedly told us they would set it on fire.” 

“We reported these threats to law enforcement multiple times, and nothing was done,” he said in his online statement.

He also claimed they were “regularly” harassed by people ​​who made it clear they “did not accept our relationship.”

Hours before his death, he shared an Instagram video discussing how the “reboot is up and moving” as he walked around Austin, Texas.
