Testimony has wrapped up at the Regina inquest into the death of Nadine Machiskinic.

Machiskinic died in January 2015 after was found unresponsive at the bottom of the laundry chute in Regina’s Delta Hotel.

The third day of the inquest Wednesday began with the testimony of Chris Keddy from the RCMP’s crime lab in Ottawa.

Keddy said blood samples taken from Machiskinic showed alcohol, methadone and three other drugs in her system. He added it was “highly likely” that the mix of drugs would have cause a complete loss of consciousness.

Keddy testified that even if Machiskinic was conscious, she would have been too intoxicated to climb into a laundry chute. However, he said there have been rare cases in which people with similar drugs in their system remain awake and mobile.

The inquest heard that one of the drugs found in Machiskinic’s system was a surgical anesthetic that would cause a person to have no perception of pain. But Keddy said some of the drugs in her system may have been administered by paramedics after she fell.

Blood tests also found high levels of sleeping medication in her system. An empty bottle of prescription sleeping pills was found along with her body.

A Delta Hotel employee testified he sent security to investigate a fire alarm that was sounding on the 10th floor. Manjit Singh says a short time later, paramedics arrived and he followed them downstairs to the laundry room, where he say Machiskinic laying on the floor.

Singh said it was a busy night and he has little memory of the comings and goings of guests. He said he didn’t know whether the hotel had a policy on keeping laundry chute accesses locked.

Toxicologist Graham Jones testified there was not enough evidence to conclude that Machiskinic would have been incapable of climbing into a laundry chute. However, under cross-examination, Jones said he has never seen the laundry chute, and couldn’t say how easy or difficult it would be to climb into.

Former Saskatchewan chief coroner Ken Stewart told the inquest that Machiskinic’s death was not immediately recognized as an incident that warranted police investigation.

Stewart said police were called later after injuries not consistent with an overdose death were found on Machiskinic’s body.

Closing statements are expected to be made Thursday morning before the coroner’s jury begins its deliberations. A coroner’s jury cannot assign blame, but can make recommendations on how to prevent similar deaths in the future.
