Editing Mircea Ionuț (section)

== Criminal career ==
Sandu assigned Mircea his first confirmed killing on 2 May 1979. Alexandru Nistor had informed police about a weapons cache controlled by the Butchers. Mircea followed him home and shot him outside the building. During later contracts, Mircea usually watched a target himself before the killing. He wrote times and addresses on loose packaging, then burned the notes after completing the assignment.

On 7 September 1990, Mircea and Dumitru drove to a privately operated liquor shop in [[Ploiești]]. Mircea entered alone and shot its owner, Gheorghe Drăgan, during the robbery. He drank from bottles inside the shop while filling crates with alcohol. Mircea vomited and fell while carrying a crate toward the car. Dumitru left the driver's seat, dragged him into the rear of the vehicle and abandoned the remaining alcohol when they fled.

Mircea began taking twelve-year-old Vladut on assignments in 1996. Vladut watched targets and reported their movements to his father. Mircea later made him carry sealed instructions. By fourteen, Vladut was delivering concealed weapons to pickup points chosen for Mircea's contracts.<ref name="vladut-early"/> Mircea checked his son's reports by making him repeat routes from memory and rejected them when the recorded times were inaccurate.

Dorian Văleanu was a Bucharest deputy who served on the Chamber of Deputies Committee for the Investigation of Abuses, Corrupt Practices and Petitions. In 1997, he obtained records of payments made by the Bucharest Butchers to police officers and prepared to present them to the committee. Mircea followed Văleanu after a constituency meeting on 18 March and shot him beside his car. Police contacts removed part of Văleanu's file and directed investigators toward a business dispute. The assassination remained officially unresolved until Bucharest Butchers records were recovered in 2025.

On 14 October 1999, Mircea took Vladut to meet [[Bănel Sârbu]]. Mircea negotiated an agreement under which [[Sârbu (tuning company)|Sârbu]] would modify vehicles for the Bucharest Butchers. Vladut handed Bănel approximately 30.7 billion old Romanian lei supplied by the organization.<ref name="sarbu-history"/>

Marku founded Porno Bucharest on 14 March 2008.<ref name="porno-history"/> Six days later, Mircea supplied him with 400,000 Romanian lei, approximately US$166,000 at the time. The money paid for recording equipment and computer storage. Marku also used it to prepare guarded rooms for the new department. Mircea received a share of its early distribution income.

[[Oskar Dirlewanger]] formally approved Porno Bucharest as an internal revenue and blackmail structure on 12 November 2008.<ref name="marku-role"/> Mircea continued collecting payments from it through 2012. Between 2009 and 2014, he killed six drivers or intermediaries who had threatened to expose the department. Those killings formed part of the 64 murders recorded by the tribunal.

Mircea continued accepting murder contracts until 2019. Recovered payment ledgers identified 52 victims by name and date. Surviving orders and witness statements established twelve further killings. The tribunal recorded a total of 64 murders against him.
