Investigators have been looking into whether the suspects had done prior surveillance of Crespo before carrying out the shooting. 

No arrests had been reported as of Tuesday afternoon.

Rio de Janeiro Secretary of Security Victor Carvalho said Crespo's killing may have been planned in advance.

'This is certainly a planned crime, where the perpetrator checked the victim's routine and waited for the exact moment to commit the crime,' Carvalho said. 'He left no form of defense for this victim.

'The perpetrator used a pistol, he got out of the car alone, he did not use any other person to carry out this approach, he left no chance of any reaction from the victim in order to flee.'

Crespo practiced civil business law and cofounded Marinho and Lima Advogados and represented clients who were victims of cryptocurrency schemes.

Metrópoles news outlet reported that in 2022, Crespo took over the defense of fellow lawyer Willer Tomaz in a dispute over the rightful ownership of a $2 million mansion that had been purchased by Richarlisson, the Brazilian soccer star and striker for Tottenham Hotspur.
