Two murders in 1997
Teitel's murder convictions centered on two killings committed during a 1997 visit to Israel. The first victim was Palestinian taxi driver Samir Balbisi, who was shot after being hired near Jerusalem's Damascus Gate. Later that year, Teitel killed a Palestinian Bedouin shepherd, reported in English-language sources as Issa Musa al-Mahamada or under close transliteration variants, near the southern West Bank.
The murders were not charged as unrelated mysteries. In the eventual prosecution, they formed the lethal core of a broader series of ideologically motivated crimes attributed to Teitel between 1997 and 2008.
A later series of bomb attacks
After returning to live in Israel, Teitel carried out additional attacks. Among the best documented was a 2008 package bomb that seriously injured a teenage member of a Messianic Jewish family in Ariel. He was also convicted in connection with an explosive device placed near the home of Hebrew University professor Ze'ev Sternhell, a prominent left-wing academic.
Other charged conduct involved weapons, explosives, incitement and attempted murder. The victims and targets came from different communities, which is why this file avoids reducing the series to one simplistic label. The common thread established by the prosecution was targeted ideological violence.
Arrest and mental-responsibility litigation
Teitel was arrested in October 2009. His case then became unusually prolonged because of disputes over his mental condition. At one stage he was found unfit to stand trial, but later evaluations and judicial rulings allowed the prosecution to proceed.
The central legal issue was not whether the underlying acts had occurred. Teitel admitted to multiple crimes. The dispute was whether mental illness removed or diminished his criminal responsibility for the murders and attacks. The Jerusalem District Court ultimately concluded that he was responsible for his conduct.
Conviction and sentence
In January 2013, the Jerusalem District Court convicted Teitel of murdering the two Palestinian victims and of attempted murder and additional weapons and violence offenses. Contemporary reports emphasized that the court found him in control of his mental faculties at the time of the crimes.
On April 9, 2013, the court imposed two consecutive life sentences plus 30 years. It also ordered compensation to victims and the families of those killed. The sentence reflected the two completed murders separately from the additional attempted murders and bomb attacks.
The Supreme Court appeal
Teitel appealed, arguing that the lower court had not given sufficient weight to his psychiatric history and claims of temporary insanity. The Supreme Court rejected the appeal in June 2016. Reporting on the decision states that the justices upheld both the criminal responsibility finding and the sentence.
The appeal matters for editorial classification because it removes ambiguity about whether the convictions remained subject to a successful challenge. The case is therefore listed as solved and adjudicated rather than merely “identified” or “suspected.”
Claims beyond the convictions
Teitel was associated publicly with a wider set of crimes and, at times, made claims about offenses beyond those proven against him. Those claims must not be treated as convictions. Israeli investigators rejected his responsibility for at least some incidents he attempted to claim, which illustrates why this dossier limits factual attribution to the conduct supported by the indictment, conviction and appellate record.
