An Oscar-nominated movie director has sparked backlash after celebrating the murder of a young Bank of America executive who was killed in a stabbing spree in Times Square.

Lexi Alexander, 52, a Palestinian-American filmmaker, shared a cruel meme about the murder of new mom Erin Piacenti, after the vice president was stabbed at-random by a mentally ill woman on Monday.

Alexander posted an image to social media the next day depicting Batman staring up at a bat signal depicting the face of alleged CEO-killer Luigi Mangione, who has since become a vigilante-style hero to legions of twisted fans.

The post attracted more than 36,000 likes but sparked a furious response from other social media users, but Alexander doubled down on her ridicule.

She claimed the backlash was being fueled by a ‘Hasbara bot farm’ – a reference to Israel’s public diplomacy arm – as a result of her calls to boycott Bank of America due to its ties to the nation.

Alexander then shared news articles criticizing her mockery of Piacenti’s death, complaining that it is her first taste of relevancy in some time in her filmmaking career.

‘Can’t get this kind of press when I promote a movie, but post a Luigi meme and they’re all over you,’ she wrote. ‘No wonder everybody constantly sounds crazy on here.’

Many online were sickened by her callous response, including attorney Mark Yzaguirre, who said: ‘A young woman was murdered while innocently walking down the street, and you are celebrating. You are absolute human garbage, and I suspect you know that deep-down.’

‘You know you’ve lost the plot when your politics are indistinguishable from that of a crazy woman that attacks random people with knives,’ another said.

Alexander, best known for her cult classic Green Street Hooligans and Oscar-nominated short film Johnny Flynton, continued to respond to criticism on X with calls to boycott the bank.

One commenter noted reports that Alexander has a net worth of approximately $1 million to $3 million, ridiculing the filmmaker’s ‘eat the rich’ stance.

‘Lol I so wish that was true,’ Alexander responded.

The filmmaker also shared a link to a Haaretz article in January about Bank of America’s calls to invest in Israeli companies.

The Daily Mail has contacted Alexander’s representatives for comment.

Her heartless response to Piacenti’s murder came as it was revealed that the, 32-year-old had just finished her first day back from maternity leave when she was fatally stabbed.

The attacker, Pamela Cisneros, 49, also stabbed an elderly man who was left in critical condition, before she was shot dead by responding police officers.

Bank of America said in a statement following Piacenti’s death: ‘We are shocked and deeply saddened by the tragic loss of our colleague.

‘She was a valued teammate who will be greatly missed. Our hearts go out to her family and all of her loved ones.’

An online fundraiser has since emerged showing Piacenti beaming as she held onto her newborn baby daughter Madison, alongside her husband Frank.

A tribute posted to the page said: ‘Erin’s life was defined not by the circumstances of her death, but instead by the way she lived.

‘Erin was deeply devoted to her family and friends, exceptionally bright and accomplished, and was someone who brought warmth and energy to the people around her.

‘Erin and Frank celebrated their second wedding anniversary this summer, had just returned from a family road trip upon her passing, and were preparing to build a life together with their new daughter. That life changed incomprehensibly in an instant.

‘Funds raised will be dedicated to supporting Madison as she grows up surrounded by the family, friends, stories, and memories that will allow her to know just how remarkable her mother was.’
