A Texan hi-tech PR and social media guru killed in a tragic car accident in Tel Aviv Saturday night has been eulogized as one of Israel’s biggest supporters in his field.

San Antonio public relations specialist Alan Weinkrantz was among three people killed when a car veered off the road and slammed into a restaurant in central Tel Aviv last night. Six other people were injured in the incident, which police say was an accident and not terror-related.

The United States Embassy in Israel notified his son Aaron of the entrepreneur’s tragic death, according to the San Antonio Express.

On Sunday, tributes to a man who spent much of the past 25 years shuttling to and from the Jewish state poured in from friends and associates in both America and Israel. Weinkrantz was on a business trip to Israel at the time of his death.

“Alan was my biggest supporter in tech, he was Israel’s biggest tech social media supporter,” Israeli entrepreneur Nir Kouris wrote on Facebook. “He was my mentor,” he said of the social media specialist.

An online fund to raise money for his funeral had already raised nearly $8,000 by early Sunday afternoon in Israel.

Police believe the fatal accident at the Furama Chinese restaurant on the corner of Ben Yehuda and Idelson streets occurred when the driver suffered a heart attack.

An investigation is still ongoing.
