A native of Vukovar, Merčep worked as an engineer before joining the Croatian Democratic Union in 1990. He then entered the local city government as the Secretary of People's Defense, where he exerted considerable power in the local police and business, esp. in preparation for the impending war. During the war, he engaged in paramilitary activities which were subsequently investigated by the Hague tribunal and covered by the Croatian newspaper Feral Tribune. At the turn of 1991, several properties owned by ethnic Serbs were blown up in Vukovar, and it was widely speculated that Merčep was behind this. In 1997 Feral Tribune released a document which confirmed exchanges of large quantities of explosive materials in September 1990 between Merčep and Branimir Glavaš. In August 1991, Merčep was briefly arrested by Croatian authorities and detained on undisclosed charges, but was soon released and moved to Zagreb together with his family, a week before the Battle of Vukovar started. Merčep later became an officer in the Croatian Ministry of Internal Affairs and he participated in the other fronts of the Croatian War of Independence, being in command of thousands of paramilitaries which were responsible for killing and expelling thousands of ethnic Serbs from areas in and around Gospić, among other places. The "Merčepovci" unit detained, tortured and killed several dozen Serb civilians at the Zagreb Trade Fair, Kutina in central Croatia and Pakračka Poljana in western Slavonia in late 1991. A total of 46 civilians were killed by the Merčepovci, three went missing and have not been found, and six were tortured but survived. A decade later, five members of his unit, Munib Suljić, Igor Mikola, Siniša Rimac, Miro Bajramović and Branko Šarić, were indicted on several criminal charges related to the Pakračka Poljana case, involving the killing of prisoners, mostly ethnic Serbs, in a field near Pakrac, and later convicted. Tomislav Merčep himself was not indicted in these proceedings.
Political career
Merčep became a HDZ member of the Chamber of Counties of Croatian Parliament in 1993. In 1995, he became the leader of the "Association of Croatian Volunteer Veterans of the Patriotic War". he remains at the head of that association. In late 1990s he quit the HDZ and instead founded his own party, the Croatian Popular Party. In 2000 he ran as a HPS candidate on 2000 presidential elections, where he received 0.85% of the vote and was eliminated in the first round.
In 2003, the Croatian weekly Nacional reported that the ICTY was "completing an indictment against Tomislav Merčep", after having talked to Franjo Gregurić, Mladen Markač, Hrvoje Šarinić and others. There were media reports in 2006 that an indictment against Merčep himself, based on ICTY investigations, was forthcoming in the Croatian legal system. In December 2010, Amnesty International stated Merčep should be prosecuted based on a series of public testimonies about crimes committed by his subordinates. In the same week, the County Prosecutor in Zagreb brought up charges against Merčep and he was arrested. In May 2016 Merčep was sentenced to 5.5 years in prison for failure to prevent the murder of 43 Serb civilians in Pakračka Poljana and other locations, committed by members of the unit under his command. In February 2017, upon appeal by the State Attorney's Office, the Supreme Court of Croatia increased his prison term to 7 years.
