Bob Lee murder suspect Nima Momeni's life was 'unravelling' - with his tech ... trends now

Friends of tech exec Nima Momeni - accused of killing Cash App founder Bob Lee - said his life was 'unraveling' in the weeks and months leading up to the alleged stabbing.

Momeni, 38, is charged with murdering Lee on April 4 in San Francisco at around 2:35 a.m. after spending around two hours with him in his married sister Khazar's apartment. 

Prosecutors have previously claimed Momeni stabbed Bob Lee in the heart after vowing to 'come down hard on him' and grilling him over his relationship with Khazar, with whom the Cash App founder exchanged intimate text messages. 

His friends and associates describe a man unraveling and battling with a drug addiction 'that made him unable to reason and speak,' fascinated with weapons and a history of abuse accusations from an ex-girlfriend. 

'This is one of those things where [we'd say], 'Nima, you're cool, we love you, but you don't make full sentences,' one long-time friend speaking on a condition of anonymity told Mission Local. 

'I don't think that's true,' Momeni's attorney, Paula Canny, said in response. 'I don't think that he had a drug problem, a serious drug problem. Based on the info that I have, I certainly wouldn't classify him as a drug addict.'

Canny has said that her client will plead not guilty. 

The friend noted, however, that he was extremely close to sister Khazar, to the detriment of other friendships.

'I don't know who Nima considered his closest group, besides his sister,' they said. 'He would do absolutely anything for her and she would do anything for him.' 

Hours before his murder, Nima had grilled Lee about his relationship with Khazar, who is married to a prominent local plastic surgeon, demanding to know whether she'd been 'doing drugs' or anything 'inappropriate' while spending time with him. 

Momeni's ex-girlfriend, who also spoke on the condition of anonymity, suggested the tech executive's father 'created a monster.' 

He expressed extreme hate for his dad,' she added, saying the family may have fled Iran to get away from him.  

Politically, Momeni was a bit hard to grasp, having donated in 2016 to Vermont socialist Bernie Sanders before giving to President Trump's re-election campaign in 2020. 

Momeni had lived the American dream, appeared to become a success in his 20s, starting Expand IT, a company that provided IT services, in 2010 after working as an IT administrator at Ace Glass. 

However, multiple friends described Expand IT as a 'hilarious s**tshow.' 

'He couldn't keep anybody and not end up chewing them out for something they didn't know — I saw it as mostly his fault,' a friend said, adding that his drug abuse - including a daily cocaine habit - likely affected him.

By 2023, it was not certain that Momeni had anyone actually employed at Expand IT, with all calls to his business number answered by an automated message using his voice. 

Canny denied this and said that Momeni had 'several contractors' working at the company, though did not appear to clarify if they were full-time employees. 

His personal life was equally problematic, according to an ex-girlfriend. 

'He was not nice behind closed doors,' she said. 'Called me probably the worst names I've ever been called.'

She also said he would be threatening and possessive and did not like when spoke to other men. She suspected he would eventually physically abuse her.
