"The neighbor said he met Momeni after Momeni held the door open for him when he first moved to the building, adding that they’ve “been good friends” ever since. He described Momeni, who was originally from Iran and ran his own IT business, as “super sweet,” though Momeni moonlighted as a DJ and “pissed off all the neighbors playing loud music at all hours of the night” and hosting parties. The neighbor said Momeni “seemed really unsettled” last week, and that he had recently been acting strangely. Just three or four days ago, Momeni allegedly approached the neighbor and asked him if he wanted to travel to Colombia. Two days ago, he randomly tried to gift the neighbor an “amazing Eames chair.” According to the neighbor, Momeni indicated that he was expecting a visit from the police, though he cast it as related to a “conflict with some girl.”
