A 43-year-old woman was found shot dead on the Pantano di Riposto seafront in the Catania area.
The victim was inside her car.
In a different area of the town on the Ionian coast, in via Roma, another woman was found seriously injured on the ground, hit by a firearm, whom the 118 staff attempted to revive but who later died in cause of the injuries sustained.
Investigations are underway by the carabinieri of the provincial command of Catania to ascertain whether the two crimes are connected.
