The police were able to identify him through a passport, reports the Tagesspiegel.
It was found on his body in the ruins of the 14th century Church of the Franciscan Monastery, which was destroyed during World War II.
It has also emerged that Damari sought help at the Israeli embassy shortly before his death.
On Friday he went to the embassy to seek help in relation to financial and technical problems, a spokesperson for the embassy said.
The embassy then contacted Damari's family and the Jewish Community in Berlin.
Damari had been invited to a dinner at the Jewish Community in celebration of Passover and had accepted the invitation. But he never turned up.
“At that point we lost contact with him,” said the spokesperson.
Passersby reported finding the body early Sunday at the site near Berlin's City Hall and the embassy said in a brief statement that it had received confirmation that the victim was one of its nationals.
Police said they have opened a murder investigation into the case and appealed for witnesses who were in the area of the church between 8 pm on Saturday April 4th and 6 am on Sunday April 5th to come forward.
