Quincy, Massachusetts’ Alexander Giannakakis arrested in Stockholm, Sweden


Alexander Giannakakis, 35, worked as a contractor and lived intermittently with his parents in Quincy, Massachusetts, United States. He had a younger brother who also lived there with their parents.

There were four fires set at Jewish-related institutions in Massachusetts in May 2019. The first two were at a Chabad Center in Arlington, Massachusetts on May 11, 2019 and on May 16, 2019.

The third fire was at a Chabad Center in Needham, Massachusetts also on May 16, 2019. The fourth was at a Jewish-affiliated business in Chelsea, Massachusetts on May 26, 2019.

Giannakakis’s younger brother was hospitalized and in a coma in November 2019. In February 2020, the younger brother became the prime suspect in an investigation into the four fires in Massachusetts in May 2019.


Giannakakis allegedly brought his younger brother’s electronic devices and papers to Sweden then re-entered the U.S. with the electronics in March 2020. In Quincy, Giannakakis told investigators that his younger brother kept property in their parents’ storage unit and there were no other locations.

However, Giannakakis had allegedly leased another storage unit himself and listed his younger brother as an authorized user. On March 22, 2020, Giannakakis allegedly went to the storage unit and removed his younger brother’s items that were relevant and material to the ongoing arson investigation, including a backpack and a bottle of cyanide.

On the same day, Giannakakis departed the U.S. for Sweden and has not returned since. His younger brother remained in a coma until his death on September 20, 2020.


On February 16, 2022, Giannakakis was arrested in Stockholm, Sweden at the request of the U.S. A federal grand jury in Boston, Massachusetts indicted him on five charges.

The U.S. plans to seek Giannakakis’s extradition to face charges in Boston. He iss charged with tampering with an official proceeding; tampering with documents and objects; concealing records in a federal investigation; making false statements in a matter involving domestic terrorism; and falsifying, concealing and covering up a material fact in a matter involving domestic terrorism by trick, scheme and device.
