By Jonathan Stempel April 27 (Reuters) - The two law firms representing Sam Altman's sister in her sexual abuse lawsuit against the OpenAI chief executive said on Monday they are withdrawing from her case.

OpenAI is facing more scrutiny over how mass shooting suspects are using its chatbot ChatGPT to plan violent attacks.

OpenAI CEO Sam Altman has issued a grim apology, admitting that the firm had failed to notify law enforcement ahead of a deadly shooting. In February, an 18-year-old named Jesse Van Rootselaar killed eight people and herself — while wounding dozens more — in a rampage that started at her home and continued at a high school in Tumbler Ridge,

The ChatGPT account of the shooter, who killed eight people in a small British Columbia community, had been banned about eight months prior to the massacre.

OpenAI CEO Sam Altman offered an apology to Canada’s Tumbler Ridge for not flagging controversial messages on its ChatGPT platform sent by the alleged shooter that killed eight people and injured over 25 others in the small mountain town earlier this year.

OpenAI CEO Sam Altman says the company is "deeply sorry" it did not flag a school shooter's ChatGPT messages to law enforcement.

The CEO's letter promised to "find ways to prevent tragedies like this in the future" by working with law enforcement and all levels of government.

According to OpenAI CEO Sam Altman, his firm is losing tens of millions of dollars due to some small words we're taught to mind every day.
