Berlin attack probe seeks supply network

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 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 on Friday in a routine police stop outside a deserted train station.
