The body of Yaron Lischinsky, an Israeli embassy employee gunned down in a possible antisemitic attack in Washington D.C. this week, was expected to arrive back in the Jewish state on Friday, officials said.

A solemn vigil was held outside the White House to remember Sarah Milgrim and Yaron Lischinsky, the young couple who worked together at the Israeli embassy in Washington and were fatally shot after an event at the Capital Jewish Museum.

The FBI hauled boxes of evidence from the Albany Park home of the man charged with killing two Israeli Embassy employees in Washington D.C. Wednesday night.

Investigators have seized writings that they believe belong to the suspect as they search for a motive in the fatal attack.

The man and the woman were shot dead outside the Capital Jewish Museum near Penn Quarter, Washington DC, and police have warned members of the public to avoid the area
