As most of the country was preparing to celebrate Christmas Eve, Germany's under-pressure authorities said hundreds of investigators would be working on the probe throughout the holiday season.
Tunisian Anis Amri, 24, is believed to have hijacked a truck and used it to mow down holiday revellers at a Berlin Christmas market on Monday, killing 12 people in an attack claimed by the Islamic State group.
The rejected asylum seeker was the focus of a frantic four-day manhunt after the rampage, but his time on the run was cut short by Italian police.
She pledged a "comprehensive" analysis of how the known jihadist was able to slip through the net in the first place.
"The Amri case raises questions," she said. "We will now intensively examine to what extent official procedures need to be changed."
"How could Europe's most wanted terrorist leave Germany?" asked the respected Die Welt daily on its website, in a nod to the growing criticism of the country's handling of the probe.
He lightly wounded one of the officers before being killed by 29-year-old police rookie Luca Scata, who has since been hailed as a hero.
Police said Amri had shouted "bastard police" in Italian before opening fire.
According to Milan police chief Antonio De Iesu, Amri had arrived in Italy from Germany via France. He had a few hundred euros on him but no telephone.
German investigators are now focusing on whether Amri had help from accomplices.
"It is very important for us to determine whether there was a network of accomplices... In the preparation or the execution of the attack, or the flight of the suspect," federal prosecutor Peter Frank told reporters.
Questions have been raised about whether enough was done to keep tabs on Amri, who was on the radar of anti-terrorism agencies in both Germany and Italy.
