Memorial Set for 2nd Victim of Minneapolis School Collapse

MINNEAPOLIS (AP) _ A memorial service is scheduled this weekend for the second victim of a natural gas explosion that caused part of a Minneapolis school to collapse.

Minnehaha Academy says on its Facebook page the service for 47-year-old receptionist Ruth Berg will be held Sunday at 5 p.m. in the lower and middle school chapel.

A service was held last Sunday for the other victim, 82-year-old custodian John Carlson.

The National Transportation Safety Board is investigating the cause of last week's explosion.

A spokeswoman for Hennepin County Medical Center said Wednesday the remaining person still hospitalized has been upgraded from critical to serious condition.
Minnehaha Academy is a private Christian school that serves students ranging from pre-kindergarten to 12th grade. The blast affected the ``upper school,'' which houses the high school.
