Christine Belford had endured a bitter divorce and custody dispute, and she was living in fear that her relationship with her ex-husband would take a violent turn.
That fear became a shocking reality Monday, when her ex-father-in-law, Thomas Matusiewicz, 68, opened fire in the New Castle County Courthouse in Wilmington, killing her and another woman, and wounding two law enforcement officers before killing himself, state police said.
It was the tragic fallout of the deeply troubled relationship between Belford, 39, and David Matusiewicz, 45, officials said.
In 2007, David Matusiewicz kidnapped their three young daughters from Newark, Del., and fled to Central America, where they were found 19 months later, living in a cramped and filthy trailer.
David Matusiewicz was sentenced to four years in prison on charges of kidnapping and bank fraud, but was released on probation in September.
Belford had told neighbors to watch her house for suspicious activity. She had a security camera installed after she suspected someone had been going through her mail and looking in the windows, neighbor Lois Dawson said.
"It's Fort Knox over there," said Dawson, 66.
Belford recently told Dawson that Matusiewicz was coming up from Texas, where he was living with his parents about 20 miles from the Mexican border.
"I know she was afraid of him and his family," Dawson said.
Matusiewicz and Belford were due in court Monday for a child-support hearing.
When Belford walked into the courthouse lobby, Thomas Matusiewicz walked up to her and shot her in the chest with a .45-caliber handgun, according to Delaware state police. Laura "Beth" Mulford, a friend who was with Belford, turned to run but was gunned down as well.
Thomas Matusiewicz then exchanged gunfire with Capitol Police, eventually falling dead near the revolving doors with a gunshot in the upper body and a self-inflicted shot to the head, state police said.
Two Capitol Police officers were shot in the chest but were saved by their bulletproof vests.
All the while, David Matusiewicz was inside the courthouse, past the security checkpoint. He and his father had entered the courthouse together, state police said, but his father had waited in the lobby about 35 minutes for Belford to arrive.
Police questioned David Matusiewicz and arrested him for alleged probation violations.
According to the probation officer's filing in federal court Tuesday, Matusiewicz had obtained permission to travel from Texas to Delaware for the hearing, and said he would stay with his uncle in Bayville, N.J. But the night before the shooting, he stayed in Elkton, Md., without permission, according to the filing.
Matusiewicz had defaulted on his $2,200 monthly child support payments and owed $9,674 in restitution, according to the filing.
Bernard August, 61, said the shooting was a blow to the Newark community of Meadowdale, where Belford and Mulford lived.
August said the women were longtime friends whose daughters played together. He described Mulford, a nurse and mother of two, as a "caring and loving person."
"It is hard to put into words what has happened here," August said. "We all suffer the losses of the people in our communities."
Belford's disputes ere not only with her ex-husband, but with his parents and sister as well.
The Matusiewicz family has accused Belford of molesting her oldest daughter — charges that she denied and which courts determined to be unfounded.
David Matusiewicz spent more than a year planning the abduction of the girls, prosecutors said. He forged his wife's name on a loan modification, sent the money to an overseas bank account, and cashed out his successful Newark optometry practice.
He and his mother, Lenore, rented a motor home and told Belford they were taking the girls — Laura, 5, Leigh, 4, and Karen, 2 — to Walt Disney World.
While on the lam in Costa Rica, Panama, and Nicaragua, David and Lenore told the children that Belford had killed herself, according to records from David Matusiewicz's criminal trial.
The kidnappings sparked national media attention, including a segment on the TV show "America's Most Wanted."
When the children were found and returned to their mother, Laura was suffering from post-traumatic stress and Leigh — who is autistic and has difficulty communicating — "was in great pain from abscessed teeth," according to court records.
Lenore Matusiewicz was sentenced to 18 months in prison.
In 2009, Belford filed a personal injury lawsuit against her ex-husband, his parents, and his sister Amy.
Lenore and Thomas Matusiewicz filed for bankruptcy in 2011, naming Belford as a creditor.
On the day he was sentenced, David Matusiewicz apologized to his ex-wife and his daughters "for the trauma they have been put through." He vowed to "rededicate myself to helping people" and supporting his daughters.
If the judge would grant leniency, Matusiewicz said, "you will never have an opportunity to see me back in a courtroom."
Matusiewicz's probation hearing is scheduled for Friday.
