Number unaccounted for now stands at 39 in Joplin

There are now 39 people who remain unaccounted for, plus four others whose families have reported them dead a week after a massive tornado hit Joplin.

The Missouri Department of Public Safety said Sunday that 39 people are unaccounted for, but that there are four more people who family members have reported as deceased. DPS says those four haven't been officially confirmed dead, however.

More than 130 people have been reported killed in the storm that hit Joplin a week ago.

The tornado — an EF-5 packing 200 mph winds — injured more than 900 people. Tallying and identifying the dead and the missing has proven a complex and sometimes confusing exercise for authorities and loved ones.
