Simatović was born in Belgrade into a Croatian family. His father Pero Simatović was born in Dubrovnik, his mother Neda (née Winter) in Bjelovar. Pero Simatović was a Yugoslav Partisan who after the war became a high-ranking officer in the Yugoslav Army, and was one of the founders of Partizan.[6] Neda belonged to the influential family Winter in Bjelovar, and was the daughter of Franko Winter (whom Simatović is named after), the founder of a law firm in Bjelovar.[7] The family has lived in Belgrade since after World War II.[8]
Franko Simatović studied at the Higher Police School and University of Belgrade Faculty of Political Sciences.[6] His mentor, colleague and personal friend was Jovica Stanišić.[6] Both were recruited into the State Security Service (SDB) immediately after studies, where they quickly rose in rank.[6] During Slobodan Milošević's rise to power, Simatović was the head of the department dealing with affairs of American agencies in Yugoslavia.[6] Simatović kept an office at Stanišić's command center in the village of Magarcevac, Croatia and both men had assumed command of regional forces in western Bosnia.[9] They also led the ‘Pauk’ (‘Spider’) operation in Cazinska Krajina, Bosnia between 1994 and 1995.[9]
Simatović and Stanišić were acquitted of all charges on 30 May 2013.[13]
However, his acquittal as well as that of Jovica Stanišić, had been overturned on 15 December 2015 by the appeals chamber, which vacated the initial verdict deemed faulty as it was based on an insistence that the men could only be guilty if they "specifically directed" the crimes.[14] On 22 December 2015, Simatović and Stanišić were granted temporary release. Back in Serbia, the two had to report to a local police station in Belgrade every day and surrender their passports to the Ministry of Justice of Serbia.[15] He and Stanišić were on provisional release from December 2015 to June 2017.[2]
MICT retrial (2017–2023)
A new trial began on 13 June 2017, and is being handled by the UN Mechanism for International Criminal Tribunals (MICT), which took over the ICTY's remaining cases as it closes in December 2017.[2][16] In December 2017, he was granted a provisional release until 19 January 2018.[17] In August 2018, only his co-defendant Stanišić was reported to still be on provisional release[18] and he did not immediately file a motion for an extension of his provision release after his return to custody.[19] Any provisional release granted to Simatović has also come with stricter conditions as well and has not faced objection from the prosecution.[20][21] As of November 2019, Simatović was still in The Hague attending the trial, while Stanistic remained on provisional release.[22] However, Simatovic was later granted provisional release from March 12, 2020, to August 13, 2020.[23] After his provisional release ended, Simatović was returned to his UN-run detention unit and again appeared in person for an appeal hearing held at a Hague court on August 28, 2020.[24][23]
...the Trial Chamber found proven beyond reasonable doubt that, from at least August 1991 and at all times relevant to the crimes charged in the Indictment, a common criminal purpose existed to forcibly and permanently remove the majority of non-Serbs from large areas of Croatia and Bosnia and Herzegovina, through the commission of the crimes of persecution, murder, deportation, and inhumane acts (forcible transfer) charged in the Indictment... The Appeals Chamber has further concluded that all reasonable doubt has been eliminated that Stanišić and Simatović possessed the requisite mens rea for joint criminal enterprise liability. Consequently, the Appeals Chamber has concluded that Stanišić and Simatović bear criminal responsibility under Article 1 of the Statute and Articles 3, 5, and 7(1) of the ICTY Statute for committing, based on their participation in a joint criminal enterprise (first category), the following crimes committed in Bosnia and Herzegovina and Croatia: (i) deportation, inhumane acts (forcible transfer), and persecution committed in connection with the takeover of Bijeljina by the Serbian Volunteer Guard as well as Serb forces and paramilitaries that worked in coordination with it; (ii) murder, deportation, inhumane acts (forcible transfer), and persecution.[27]

Simatović was released early on September 1, 2023, due to seriously deteriorating health.[28][29][30]
