Daniel Kaufman, 42, of Rialto, who ran the coffee shop in building 3 at the Inland Regional Center, is among those who were killed in Wednesday’s shootings, according to social media posts and news media.

“I am sad to report that Daniel has been positively identified as one of the fatalities at the scene,” Ryan Reyes, Kaufman’s boyfriend, posted on Facebook. “Thank you all for your love and support. I love you Daniel, and I will forever miss you.”

Reyes told the Los Angeles Times that he dropped Kaufman at work Wednesday’s morning and they exchanged text messages.

Reyes, also of Rialto, spoke to reporters Wednesday, and said it took him four and a half hours to find out his boyfriend was hospitalized.

Reyes said that initial reports were that Kaufman survived, but he learned Thursday morning that it wasn’t the case.
