Authorities have recovered human bones from a south Phoenix storm drain after workers on a cleaning crew spotted them at the bottom of an access shaft.
Maricopa County sheriff's spokesman Sgt. Brandon Jones says workers spotted what appeared to be human remains early Wednesday, at 43rd Ave and Wier.
Officials had to wait until about 9 a.m. before fire crews determined the air was safe for homicide detectives to climb down about 30 feet to the bottom of the drain.
Jones says detectives did not recover an entire skeleton and re-entered the drain with scuba masks -- they then found an additional bone.
The remaining drainage pipes have been cleared.
He says detectives doubt the person accidentally ended up in the drain. A body may have been dumped into the drain, or washed down from upstream.
There's no information yet on if the bones belonged to a male or female, but we do know they are that of an adult. The medical examiner will now determine identity and cause and manner of death.
The intersection was reopened as of 2:30 p.m.
