The man who allegedly ran down about 20 people in Melbourne's CBD today, killing four and injuring 20 others, has a history of drug use, violence and psychological problems.
James "Jimmy" Gargasoulas has been identified as the 26 year-old who was bailed by a bail justice on the weekend after he was arrested in St Kilda for a number of alleged offences, including family violence and stealing another car, sources claim.
He was staying with his mother in a public housing flat in Windsor, where he allegedly stabbed his brother, Angelo, in the early hours of Friday morning.
The car Mr Gargasoulas allegedly used to run down pedestrians belonged to 76-year-old Gavin Wilson, who lives at the housing commission flats and had dated his mother.
Mr Wilson told media he came into his flat with a Bible, sat down and started burning it before throwing the burning book into his face.
Mr Gargasoulas, whose also known as Dimitrios, is known to police for drug-related issues, family violence assaults and has "an extensive family violence history," according to Victorian police.
