At first it seemed like another "nut call" to the newsroom.

But, when Jose Ferreira called WISN in Milwaukee and confessed to killing a 7th grade girl 30+ years ago, he had a lot of details. 

"His story was very detailed — disturbingly so," Chris Gegg, the station's news director, said in a statement emailed to The Associated Press. 

Gegg didn't elaborate, but he said the station called police because of "several red flags." 

"It's been 33 years since she's been gone," the girl's mother, Carolyn Tousignant, said after Ferreira was arrested. "I've been praying for this day." 

Carrie disappeared after she was suspended from school for roaming the halls. Tousignant said her daughter got kicked out on purpose so she could go to a house party.

Ferreira has been charged with second-degree murder and Prosecutors say he is responsible for the death of 13-year-old Carrie Ann Jopek, who went missing in 1982. 

Back in 1982, Tousignant said the school called and gave her the option of picking the girl up from the office, but she chose not to because they lived only a block away. It's a decision she has come to live with. 

"I blame myself sometimes," the girl's mother said. "She would've snuck over there anyway." 

The case went quiet until someone repairing an old deck came across the girl's body 17 months after her disappearance. 

"I never put it out of my mind," Tousignant said. "Every time I watch 'Cold Case' or some other detective show, I would hope and pray one of these days we get the person who did that to Carrie."
