After 40 days of dead ends, a strange $2,000 septic-tank pumping invoice at 4 A.M. from Tommaso Cioni’s house raises suspicion

At first glance, it appeared to be an ordinary service receipt issued by a local waste-management contractor. But the details printed on the form quickly raised concerns among investigators reviewing the file.

The service had been requested at 4:03 A.M.

The address listed on the invoice belonged to the residence of Tommaso Cioni.
