UPDATE 10.15AM: Detectives have located a fourth bullet casing at the scene of a drive-by shooting in Harlaxton, Toowoomba.
While ballistics experts from Brisbane travel to Toowoomba, police have extended the door-knock area around the Ruthven St home that was sprayed with bullets about midnight while three people were inside.
Detective Inspector Dave Isherwood said there was no suggestion the 60-year-old grandmother, 29-year-old mother and six-year-old boy had been targets.
"The residents have only been there a very short time and there is no connection at this stage," he said.
"The people are respectable people and there's no nexus between the members of the house and the shooting."
The bullets from a high-powered rifle hit the exterior of a bedroom wall in which at least one member of the household is believed to have been inside.
Insp. Isherwood said it was lucky the family had been sleeping at the time.
"Thankfully they were in bed asleep at the time," he said.
"The shots went into the bedding area.
"The three people were in that side of the house at the time."
Insp. Isherwood said police this morning had extended the area to be door-knocked by uniform officers and detectives in an effort to determine the motive behind the shooting.
He said the house was not a known address to police for crime but others in the area were known to have been troubled crime spots in the past.
"There's nothing to suggest the house should be the target," he said.
The Chronicle understands residents in a house two doors up the street had been questioned by police last night.
Insp. Isherwood said police were yet to determine the specific type of gun the shooter had used.
"We really don't know but we believe it may be an assault rifle," he said.
"But until ballistics come up, we won't be able to determine the type but it is definitely a high powered firearm rifle.
"It is not a revolver or a concealable handgun."
Anyone with information is urged to contact Crime Stoppers on 1800 333 000.
8.50AM: Toowoomba mother Karllee Robertson says she no longer feels safe living in her own home after a drive-by shooting last night.
Ms Robertson said she was woken by three loud blasts around midnight, initially thinking her car had been shot out.
But it was her neighbour's house that had been targeted.
"I heard three gun shots and a car take off, and I didn't think anything of it," she said.
"Then 10 minutes later, there were police out the front and I heard they found some shells behind my car.
"I came out and seen them and asked if someone had shot out my car and they said no, they shot next door."
The mother-of-three said bullet shells littered the ground behind her car parked out the front of her home on Ruthven St.
She said her neighbours had moved in about three weeks ago.
Ms Robertson said violence was relatively common in the area but the family had stayed.
She now no longer feels safe in her home in which she lives with her three children Kiarah, 16 months, Jayden, 5, and Dylan, 9.
"We've lived here for five or six months and it's crazy," she said.
"Heaps of bad stuff happens around here.
"We've even had people jump out of cars and run down our driveway for help when they're getting bashed by their boyfriends and stuff.
"I said to Scott (partner) last night when it happened that I don't want to live here anymore."
Ms Robertson said she didn't know her neighbours well but knew a young boy lived in the house.
