Investigators seek supply network for slain Berlin attacker

MILAN — Investigators on Saturday worked to determine if the Berlin Christmas market attacker got any logistical support to cross at least two European borders and evade capture for days before being killed in a police shootout in a Milan suburb.

Tunisian fugitive Anis Amri’s fingerprints and wallet were found in a truck that plowed into a Christmas market in Berlin on Monday night, killing 12 people and injuring 56 others. Despite an intense, Europe-wide manhunt, Amri fled across Germany, into France and then into Italy, traveling at least part of the way by train, before being shot early Friday in a routine police stop outside a deserted train station.

The Islamic State group has claimed responsibility for the Berlin attack, but so far little is known about any support network backing up the 24-year-old fugitive.

Italian investigators were working to see if the Tunisian had any connections in the Milan area. Italy was his port of entry into Europe in 2011 and he spent more than three years in Italian jails on Sicily. But an anti-terrorism official said there was no evidence that he had ever been in or around Milan before Friday’s shootout.

In Tunisia, the Interior Ministry announced the arrest Friday of Amri’s nephew and two others suspected of belonging to the same extremist network.

The ministry said in a statement that Amri, through an alias, had sent his 18-year-old nephew Fedi some money through the post office to join him in Europe and join the Abou Walaa network.
