LAKEVIEW, Ore. -- An autopsy performed on a Lakeview man who died in police custody found the cause of death to be probable acute methamphetamine poisoning.

Lake County Sheriff Phil McDonald reported the finding yesterday.

Two state troopers arrested 44-year-old David Turnbull at a grocery store parking lot after finding him with a knife and a pipe containing methamphetamine.

The handcuffed man collapsed shortly after midnight Thursday as the troopers walked him toward the Lake County Jail.

Turnbull, a convicted felon, died 30 minutes later at Lake District Hospital.

Lakeview is in south-central Oregon, near the California and Nevada state lines.
