Police were searching Friday for the man who fatally gunned down a clerk during a robbery at a kosher liquor store in Brooklyn the previous day.

Investigators released surveillance video of the suspect, seen above, which shows him barging into the Brooklyn store.

Yoseph Robinson, 34, was shot and killed during a robbery at MB Vineyards on Nostrand Avenue near Avenue J in Midwood around 9:30 p.m. Thursday.

Sources say Robinson and his girlfriend were working in the store when the gunman walked in and demanded that Robinson's girlfriend hand over her bracelet. Robinson was shot several times in the chest and arm while trying to protect her.

He was taken to Kings County Hospital, where he was pronounced dead.

Friends said Robinson was well known and well-liked in the community.

"We spoke briefly, you know, and he went inside the store to continue his duties,” said a friend. “I went to Target to get a few things and came back to this."

“I used to see him every morning,” said another. “He was a really sweet guy.”

"He was a very friendly person. Wherever you went, I guess, he spoke, you know, to everyone as a friend," said a third.

Robinson was born in Jamaica as Chester Robinson. According to his website, he lived a "reckless lifestyle" before turning to Orthodox Judaism.

"He's not one or the other, he's both. I mean, it didn't really, you know, he said, 'I don't want to be identified as just a black man; I don't want to be identified as just a convert,'" said another.

Robinson's website shows him rapping with verses from the Torah, praying, and preparing to release a book about his journey from the street to scripture.

A $12,000 reward is being offered for information on the suspect. Anyone with information is being asked to contact Crime Stoppers by calling 1-800-577-TIPS, by texting TIP577 to CRIMES, or by going to NYPDCrimeStoppers.com.
