HER SISTER CALLED 911 TO REPORT A BREAK-IN. THEN POLICE LEARNED WHAT REALLY HAPPENED TO 17-YEAR-OLD SYNDI BIERMAN.
On the evening of February 18, 1989, Syndi Sue Bierman came home from work and invited two friends over to watch a movie at her family’s home in Kansas City, Kansas.
Syndi was 17 years old. She was an honor-roll student, a yearbook photographer, and a member of her school’s drill team. She had played softball and volleyball, enjoyed music, and had been accepted to the University of Kansas.
She had her whole life ahead of her.
By the following morning, Syndi was dead in her bedroom, and the person who called police was her own sister.
THE NIGHT SYNDI WAS KILLED
Syndi lived upstairs in her parents’ home. Her older sister, Shari Bierman, lived in a finished basement apartment with her two young sons.
According to Syndi’s family, Shari and two male acquaintances, Conrad Joseph Hernandez and Archie “A.J.” Owens Jr., were at the house while Syndi and her friends watched television.
Syndi’s friends later told investigators that Shari came upstairs more than once and asked whether they were spending the night and when they planned to leave.
The friends eventually left. Syndi remained home.
According to testimony summarized by the Kansas Supreme Court, Shari, Hernandez and Owens left the house, dropped Shari’s children off at Owens’ apartment, and then returned to the Bierman home.
Hernandez later testified that the three had discussed stealing property from Shari’s parents. He claimed Shari directed them to a construction site, where they picked up two-by-fours in case they needed to knock someone out.
He said Shari told them her sister would be home, but that if they were quiet, they could take the property without waking her.
That is not what happened.
INSIDE SYNDI’S BEDROOM
According to Hernandez’s testimony, he and Owens went upstairs carrying the boards. Syndi began to wake up and asked who was there.
Hernandez testified that he struck Syndi several times with a two-by-four and that Owens also hit her. Syndi fell from the bed and began screaming.
Hernandez said he put a pillow over her face. He testified that he later heard Owens tell Shari to “get her,” followed by Shari shouting at her sister and a thumping sound.
He also testified that Owens told Shari to get knives and that she returned with two knives from downstairs.
Hernandez denied cutting or stabbing Syndi while testifying at trial. But another witness testified that he had admitted cutting Syndi’s throat. A second witness also testified that Hernandez told her he had cut Syndi’s throat and that Owens had stabbed her.
The medical examiner found that Syndi had been beaten, cut and stabbed. She had defensive wounds on her hands and arms. The cause of death was blood loss.
Syndi fought for her life in her own bedroom.
THE 911 CALL
At approximately 3:11 a.m. on February 19, Shari called a Wyandotte County dispatcher and reported that the house had been broken into. She said she believed someone might still be inside.
About 30 seconds later, she called back and reported that her sister was on the floor and there was blood everywhere.
When officers arrived, Shari directed them toward the stairs. Syndi was found in her upstairs bedroom. Parts of the home had been ransacked, and property was missing.
Shari initially told police that she had left around 11 p.m., returned around 3 a.m. and discovered the break-in and her sister. She said no one else had been at the house with her that evening.
But when investigators spoke with Syndi’s friends, they learned that other people had been there.
Shari eventually acknowledged that Hernandez and Owens had been at the house with her, but maintained they would not have stolen property or killed her sister.
Investigators later found stolen items from the Bierman home at Owens’ apartment. Court records list a computer, printer, VCR, camera, watches and other property among the items taken.
WHAT WAS THE MOTIVE?
Syndi’s family has said they heard two different explanations and may never know exactly what the three intended when they returned to the house.
One possibility was that they planned to rob the home and Syndi woke up during the crime.
The other was a reported theory that Shari and the men had planned to kill Syndi’s parents for insurance money.
That second account remains a theory described by Syndi’s family, not an established finding in the court opinion. The Supreme Court record includes testimony that the three had discussed stealing from the home and that they returned carrying boards.
There was also evidence of tension between the sisters. Syndi’s boyfriend testified that, days before her death, Syndi told him Shari had threatened her and that she was afraid to go home. Friends also testified about conflict between them.
Whatever the original plan, a jury ultimately found Shari guilty of premeditated first-degree murder.
SHARI’S ACCOUNT
At trial, Shari gave a different version of events.
She testified that when the three returned to the house, she did not know Syndi was home. She said Hernandez began throwing things around upstairs, so she ran to her basement room and locked herself inside.
Shari claimed Hernandez later kicked in the door and threatened her. She said she was afraid of him.
Hernandez denied threatening her. The jury heard both accounts and found Shari guilty.
THE INVESTIGATION AND COURT CASES
On February 21, 1989, Hernandez and Owens were charged with first-degree murder and theft. Shari was initially charged with theft and aiding a felon. Two days later, she was also charged with first-degree murder.
After learning police were searching Owens’ apartment, Hernandez and Owens left the Kansas City area with others. Hernandez was apprehended in Oklahoma. Owens made his way to Arizona, where he turned himself in to the FBI and was returned to Kansas.
Hernandez pleaded guilty to first-degree murder and agreed to testify against Shari and Owens.
Shari and Owens went to trial. Both were convicted of first-degree murder and theft. Syndi’s family said all three were sentenced to life in prison.
Both Shari and Owens appealed. In 1991, the Kansas Supreme Court affirmed their convictions.
REMEMBERING SYNDI
Syndi’s family described her as a girl whose smile could light up a room. She loved her family, cared about other people and stayed busy with school, church, sports and music.
She was preparing for college. She had dreams and plans that should have been hers to pursue.
Instead, her parents came home to police at their house and learned that one daughter had been murdered, and that their other daughter would be convicted in her death.
Syndi was only 17 years old.
Please remember Syndi Sue Bierman and keep her family in your thoughts. 🕯️🖤
