Basicaly, there was this mayor called Celso Daniel, from the Workers Party (PT). He was kidnapped and killed the year Lula (also from PT) was ellected. Not only him was killed, but also:

>his kidnapper, who the police was investigating
>other guy who helped kidnapping him
>police investigator who called him the day before
>the fucking waiter who served him the night he died
>some random dude who saw the waiter getting shot
>the undertaker who recognized his body dumped on some road
>the coroner who atested he was tortured before killed
All of them were shot multiple times. Some in the street, others in their own house.

Celso's brother says that he (Celso) knew and accessorized a scheme of money detouring to PT. It envolved transport companies and also José Dirceu (who later was arrested for Mensalão, a huge scheme of buying congressmen votes).

The guy who was driving Celso's car when Celso was kidnapped escaped without a scratch. Police believes he orchestrated the killing.

Second image is about his wife, Miriam Belchior: she was bought by PT. After Lula was elected, she became his 'special advisor', and all subsequent years she was given some random minister position.

The point of the story is that PT rose to power by killing EVERYBODY who risked jeopardizing their winning. They were also involved in many bribe scandals during Lula and Dilma mandates as presidents, so basically 'la plata o el plumo': Pablo Escobar's famous policy of 'silver or lead', i.e: accepting money or accepting bullets.
