SYDNEY, Oct 22 - The NSW teacher was shot in the exclusive suburb of Karen on Thursday during what was believed to be a botched robbery reportedly involving assailants on motorbikes.
"It is important for them (Department of Foreign Affairs) to keep on pushing until it is certain as to what caused her death," Maina's lawyer told ABC Radio on Sunday.
However, it's possible the shooting was targeted with Maina's lawyer telling the ABC she was kneeling during the shooting.
"The shooting happened when she was kneeling and someone was standing," the lawyer said.
It's believed that Maina, originally from Armidale, had just dropped off her son at a friend's home.
Security company Insight Secure, which monitors local incidents, said a caucasian woman was killed by "unidentified assailants" and "a 9mm cartridge was recovered at the crime scene", Fairfax Media reports.
