NEW YORK -- Wesley LePatner, a senior executive at Blackstone, was laid to rest on Thursday. She was one of four killed after a gunman opened fire inside a Midtown Manhattan office building earlier this week. Her funeral services were held at Central Synagogue on the Upper East Side. The Yale graduate was a senior managing director at Blackstone.

Officials said the gunman fatally shot himself after his attack, which set off a chaotic scene that rippled out into the heart of Manhattan during rush hour.

Investigators are combing through evidence in the wake of New York City’s deadliest mass shooting since 2000, trying to figure out more about the gunman who unleashed an assault-style rifle in Midtown,
