Both brothers own and run an air freight company; they import goods and one of their customers is Maloud Senac. Daniel doesn’t have a police record but his brother Gary does: a GBH conviction for which Gary was sentenced to eight years – he got out last year after doing four.
Nixon suspected the Pfeiffers brought in 30k of cocaine from South Africa and some of it was being delivered to Maloud Senac. On the police raid nothing was found, however, Gary was missing and so was Maloud’s daughter Salma, (she’s believed to be in a relationship with Daniel).
Gary did show up for a brief time when DCs Terry Perkins and Stevie Moss witnessed him pull up on a canal side and shoot their delivery driver and police informant Kenny Bordmann.
