Bus 174 hostage crisis (2000)
This was broadcast live by most Brazilian national television channels. Sandro Rosa do Nascimento was a survivor of the Candelaria church massacre of July 23, 1993. On June 12, 2000 Nascimento boarded a public bus armed with a .38 caliber revolver, with the intention to rob the passengers. Moments after Nascimento announced the robbery, a passenger signaled to a vehicle from the Rio de Janeiro military police, prompting the police to intercept the bus. Sandro then took the bus passengers hostage. A number of events followed. At 06:50 PM local time, Nascimento exited the bus, using schoolteacher Geisa Firmo Gonçalves as a human shield. As Nascimento's attention was being held in one direction, an officer armed with a submachine gun approached Nascimento from behind. Just prior to the officer reaching him, Nascimento turned directly toward the officer and reacted by jerking away from the officer, falling to the ground, taking Gonçalves with him. The officer reacted by continuing his advance and firing two or three shots at Nascimento while doing so. The first shot struck Gonçalves in the face while none of the other shots struck Nascimento. Nascimento then proceeded to fire three shots at Gonçalves, killing her. Nascimento could be seen to be alive at the time he was placed into a police vehicle. Some time after being taken into custody, he died of asphyxiation. There were later assertions that Nascimento was intentionally killed by the police, and that his death was revenge for the public nature of the hostage event. The officers who took him into custody were charged with murder; after the jury trial, they were found not guilty. Gonçalves was shot four times. Police reports concluded she had been shot once in the face by the advancing police officer and then three times in the back by Nascimento in the ensuing struggle. The officer's shot was ruled unintentional by a court.

This is the only hostage crisis incident I could remember that happened live on TV.

Hostage crisis's are fascinating to me, they are one of my favorite types of crimes

There was a hostage crisis at a Russian school in 2014. A 15 year old student named Sergey Gordeyev shot and killed his Geometry teacher and held his class hostage. He additionally shot and killed an officer outside the classroom, and injured another. After about an hour, his father told him to give up, wearing a bulletproof vest, and he surrendered to the police. It’s an interesting case, it’s actually the first school shooting by a student in Russia excluding the Beslan School Siege (which was a terrorist attack by multiple people).

Janet M. Smith took her own cat "hostage" in a grocery store in 1994. She was shot dead while lunging at officers, cat still in her hands.

Thomas Edward Smith, who took his estranged wife hostage at a 7-Eleven store, killed a store employee and committed suicide in January 1986. The television's cameras managed to took a shot from Smith's fatal shot to the head.

Willian Augusto da Silva took 39 passengers on a bus travelling over the Rio-Niteroi bridge hostage. He was armed with a fake pistol, a stun gun, gasoline, and a knife. He was later shot by police, the only casualty. He wanted to copy the onibus 174 hijacking and go down in history. He also wore a skull mask, but I don't know if he was interested in Suzano or got the idea from it.
