Two men have been arrested on suspicion of murdering the prominent Brazilian music producer, Almir Chediak.
Rio has a reputation for violent crime
Mr Chediak and his girlfriend were kidnapped and driven to the district of Petropolis in Rio de Janeiro state on Sunday night, where he was shot dead within earshot of his girlfriend.
His body was left by the roadside and his girlfriend, Sanny da Costa Alves, was then released, physically unharmed, at another location.
One of the two alleged kidnappers was detained by police on Monday night. The man accused of pulling the trigger was captured on Tuesday morning.
Mr Chediak, 52, was best known for putting down in musical form the melodies created by such Brazilian stars as Caetano Veloso, Gilberto Gil and Antonio Carlos Jobim.
Mr Chediak's murder has shocked the Brazilian music industry.
Aside from transcribing the melodies of some of Brazil's most famous musicians, Chediak was also a music teacher who had taught some of Brazil's top stars, including Gal Costa, Tim Maia, Cazuza and Morares Moreira.
His company Lumiar also produced CDs of Brazilian music.
He was due to be buried on Tuesday at 1400 local time (1700 GMT) in Caju, Rio state.
The first suspect detained, Generino Pedro da Silva, gave police the name of his alleged accomplice.
The pair are alleged to have stolen items from the home of Mr Chediak.
Mr dos Prazeres, as he is known, was reportedly detained on Tuesday morning while preparing to flee the Rio area.
