‘Don’t kill my baby!’
Were these the last words of a pregnant murder victim or a warped teen’s sick humour?
The police could find no real motive
ASaturday night in April 1990, and Nancy and Richard Langert had just returned from Nancy’s father’s birthday party to their home in Winnetka, Illinois.
The birthday wasn’t the only thing the happily married couple had to celebrate.
Back in January, Nancy, 25, had announced that she was expecting their first child telling friends, ‘we have everything going for us, this is going to be our year.’
Instead, the young couple fell victim to a brutal crime that shocked the peaceful community to its core.
For, on that Saturday night, an armed intruder had broken into their townhouse and was lying in wait.
Handcuffing Richard, 28, he then shot him in the back of the head with a .357 Magnum revolver, and then turned the gun on Nancy.
She cowered on the floor in the corner of her basement, begging for the life of her unborn child, holding her arms over her tummy.
‘Please don’t kill me, please don’t kill my baby!’ she begged desperately.
But the heartless killer fired directly into her belly.
An autopsy later revealed the bullet had hit the growing baby, killing it instantly.
Nancy was shot again, the bullets hitting her in her side and elbow.
Then the heartless killer fled the scene.
The next morning, when the couple failed to turn up to church, Nancy’s father went to their home.
He discovered their bodies, lying, face up, in the basement. As she lay dying, Nancy had managed to use her finger to draw with her own blood a heart and the letter ‘U’ on the floor.
She chose to spend her last moments of life to tell her family that she loved them. The intruder had rifled through Nancy’s bag and ripped boxes the couple had been packing for an upcoming house move.
But nothing had been taken, not even cash.
For six months, the police tried desperately to find leads, but kept hitting dead ends. There seemed no real motive.
Richard had been a keen athlete, loved hosting parties for family and friends, and Nancy had sung in the church choir and performed in the community theatre.
Who would want to murder such an innocent, lovely couple?
But, in October, a student at the New Trier Township High School, went to the police with information.
His classmate David Biro, 17, known for his sarcasm and perverse humour, had been bragging about how it was he who’d shot Richard and Nancy.
Biro was on the high school cross-country running team, skinny, with slicked-back hair and roughlooking tattoos on his arms.
He was a loner, and suffered from mental health issues.
And he’d made outrageous, far-fetched claims before.
He’d previously told his fellow students he was a hired assassin, a drug dealer and a street-gang member.
But this time, the police took his claims seriously.
Especially because Biro had mentioned details of the murders that had never been publicly released.
He’d also been seen, wearing dark clothing, near the murder scene on the night of the slayings.
The police had been made aware of Biro three years before, after he’d allegedly tried to poison his parents, along with his brother and sister, with tainted milk.
He’d ended up in a psychiatric hospital in Chicago.
The police wasted no time in arresting Biro, and found a glass cutter, handcuffs and a .357 Magnum in his bedroom.
David Biro was charged with the first degree murder of Richard and Nancy Langert and with the intentional murder of their unborn child. In November 1991, appearing before the Cook County
Circuit Court, Biro denied the charges.
Taking the stand in his own defence, he sensationally claimed that another classmate had committed the murders and confessed to him,
Biro claimed he’d agreed to hide the weapon, then said he’d gone to buy the handcuffs and glass cutter, so he could ‘re-create the murder’ in his mind for a ‘better understanding’ of what his friend had done.
Biro said that, piecing together information from the killer’s confession to him, along with newspaper reports, he’d been able to gather information about the murders.
Biro admitted that he’d boasted that he’d killed Nancy and Richard – but only in jest.
‘Whatever was said in those conversations was said in a joking manner,’ he testified. ‘I was trying to shock these people.’
But when New Trier Township High School student
Phu Hoang took the stand, and described Biro’s so-called joke, it didn’t seem so funny.
Phu told the court that Biro had cut glass panes out of the Langert’s patio doors and waited for them to get home. He described how the defendant had told him that Nancy had begged for her life of her unborn baby and Biro had accidentally fired a shot when surprised by a dog’s barking.
Phu said Biro told him he offered to lock the Langerts in the basement and leave. But Nancy glimpsed his face and he’d felt he had no option but to kill them.
A red notebook found in his room contained news articles about the murders.
But the fact remained…there seemed no motive whatsoever.
No-one could prove Biro had ever met the Langerts, even though his parents were casually acquainted with Nancy’s parents – and Biro had even accompanied his mother to the Langerts' funeral.
Had a sick joke landed this troubled teenager in the dock? Or was he really a cold-blooded murderer?
