Blood test results 'critical' in case of Peter Loeschnauer, charged over death of Lachlan Seary

Peter James Loeschnauer, 29, has been charged with manslaughter, aggravated dangerous driving, drink-driving and drug-driving.

He was allegedly drunk, on drugs and speeding when he rear-ended a Toyota Corolla driven by Lachlan Seary on the Monaro Highway, near Hume, on March 8.

Police have said the impact of the collision spun the 19-year-old Canberra Brave ice hockey player's vehicle off the road and into a tree, killing the teenager.

Mr Loeschnauer has not been required to appear in the ACT Magistrates Court on either of the two occasions his matter has been mentioned.

His solicitor, Tom Taylor of Hugo Law Group, on Thursday told the court a second blood sample taken from the 29-year-old after the crash had been sent for testing.

Mr Taylor indicated the results, expected early next month, would shape the direction of the case.

"The matter will most likely resolve in some way, but the bloods will be critical to that," he said.

Magistrate Beth Campbell granted Mr Taylor's application to adjourn the case until September 16.

After charging Mr Loeschnauer earlier this year, ACT Policing said speed cameras on the Monaro Highway had captured his Honda Civic travelling at 149km/h in a 100km/h zone "immediately prior to the collision" with Mr Seary's car.

Further analysis of CCTV recordings from along the highway were said to show he had also been rocketing along at more than 160km/h in an 80km/h area "moments before" the impact.

"Investigations indicated that after being hit from behind, the Corolla was spun from the roadway into the centre median where it rolled and struck a tree," police said in a statement in April.

"The driver of the Honda Civic, who was not injured, provided a positive screening test for alcohol and drugs at the scene, and was conveyed to hospital for mandatory blood testing."

Mr Loeschnauer allegedly returned a blood alcohol reading of 0.186 - nearly four times the legal limit - and a positive result for MDMA.

Detective Inspector Donna Hofmeier has previously described Mr Seary's death as senseless and completely avoidable.

"As a result of one man's reckless actions, a young man has lost his life in the most tragic circumstances," the senior police officer said.

"The 19-year-old was a completely innocent party in this collision.

"There was no street racing and no interactions between the two drivers before the two cars collided.

"We regularly say we are frustrated with drivers that do the wrong thing but in this case it's more than frustration, it's a sense of needless loss.

"We have a young man dead and another facing serious criminal charges for his actions."
