Mario Bozzoli was killed by being thrown into the furnace of the foundry.

Giacomo Bozzoli appears to have taken flight with his wife and son before the supreme court upheld his conviction on Monday, making his life sentence definitive.

His Maserati Levante SUV was detected at Manerba and Desenzano, in the province of Brescia, early on June 23.

A European arrest warrant has been issued for him.

His father-in-law said he believes he is somewhere in France.

His passport may have expired.
