Very good detective work. “Moto” is French slang for motorcycle.
Let’s hope this gets solved soon.
Many thanks - and the killer rides a motorcycle. What a chilling case.
The weapon, an automatic pistol 11.43mm, is said by Sud-Ouest to be found in the milieu of organized crime. It is not an ordinary gun. The killer dropped the charger at the scene of the crime, but an inspection found no trace of DNA the charger had been totally cleaned. All this seems to indicate some careful planning. Those guns certainly have a reputation.
Back in 2007, Le Figaro, commenting on an outbreak of violence by crime gangs in Grenoble, commented that the weapon was an automatic pistol 11.43mm the signature of a settling of scores.

But I think Basques might have them as well.
