Knoxville, Tennessee — Emma Walker was remembered by her family and friends as much more than the teenage cheerleader whose murder shocked her community.
Born and raised in Knoxville, Emma was a 16-year-old honors student, daughter, sister and friend who dreamed of becoming a neonatal nurse. She attended Central High School and joined the cheerleading team as a freshman in 2014.
Her mother, Jill Walker, later emphasized that Emma should not be remembered only for the way she died.
“She was so much more than that,” Jill said, describing her daughter as someone who was independent, funny, stubborn and full of personality.
Emma loved babies, animals and spending time with people. Friends said cheerleading was one of her greatest passions, and she enjoyed performing at football games and being part of the school community.
Emma Walker and William Riley Gaul’s Relationship
Emma met William Riley Gaul, a football player at Central High School, after joining the cheerleading squad. At first, the relationship appeared ordinary. Emma’s mother initially viewed Gaul as a friendly and likable teenager.
But over time, family and friends began noticing troubling changes.
Friends said Gaul allegedly became controlling about Emma’s activities, friendships and clothing. The couple also reportedly had intense arguments through text messages and social media.
Emma’s mother recalled discovering a threatening message that allegedly said, “I’ll see your name in the obituary.” When confronted, Gaul reportedly claimed he had written it because he was angry.
For Emma’s parents, however, it became another major warning sign.
Her Parents Tried to Separate the Couple
As Gaul’s behavior allegedly became more concerning, Emma’s parents prohibited him from coming to their home and encouraged their daughter to end the relationship.
Despite those concerns, Emma and Gaul continued seeing each other on and off.
By the fall of 2016, Gaul was attending a nearby college while Emma remained in high school. Her parents became increasingly worried and began monitoring her activities.
When Emma spent more time away from Gaul, her father noticed something important.
“She did become like her old self again,” Mark Walker later recalled, saying his daughter began coming out of her room, eating dinner with the family and spending more time with them.
Emma Finally Ended the Relationship
By November 2016, Emma had decided to end the relationship for good. But investigators later alleged that Gaul refused to accept the breakup.
According to accounts from the case, he reportedly attempted to get Emma’s attention through increasingly alarming behavior, including allegedly faking a kidnapping and sending anonymous messages.
On one occasion, Emma believed she had seen someone dressed in black outside her home. She became frightened and contacted Gaul, who reportedly offered to come check on the situation.
Her parents later became suspicious that Gaul himself may have been connected to the strange incidents. Emma’s family was increasingly concerned about what could happen next.
Emma Walker Was Found Dead in Her Bedroom
In the early morning hours of November 21, 2016, Emma was inside her family’s Knoxville home. Her mother went to wake her for school that morning and instead discovered that her daughter had been fatally shot.
Investigators determined that one bullet struck Emma behind the left ear. A second bullet entered her pillow. Police found two bullet holes in the wall, indicating that the shooter had fired into Emma’s bedroom from outside the house.
The teenager was only 16 years old.
Investigators Quickly Focused on Her Ex-Boyfriend
As detectives interviewed Emma’s friends and relatives, Gaul’s name repeatedly surfaced. Authorities learned about the couple’s troubled relationship, alleged threats and his refusal to accept the breakup.
Several of Gaul’s friends also told investigators about suspicious behavior.
One friend reportedly said Gaul had stolen his grandfather’s gun. Another alleged that Gaul had asked questions about removing fingerprints from a firearm and getting rid of a gun.
Investigators eventually questioned Gaul. He denied killing Emma and reportedly told detectives that he would hurt himself before hurting her. He claimed he was in his dorm when the murder occurred.
But investigators found evidence that contradicted his account.
Gaul’s phone was reportedly placed near Emma’s home around 3:45 a.m., around the time investigators believed the shooting occurred. Two of Gaul’s friends later worked with police to help recover the murder weapon.
Gaul was arrested on November 22, 2016, one day after Emma’s death.
William Riley Gaul Was Convicted of Murder
Gaul was later indicted on seven criminal counts, including first-degree murder, especially aggravated stalking, tampering with evidence and employing a firearm during a dangerous felony.
During his 2018 trial, his defense argued that even if Gaul fired the gun, he did not intend to kill Emma and had allegedly wanted to get her attention.
Prosecutors argued that the shooting was premeditated, pointing to evidence that the gun was deliberately fired toward Emma’s bedroom.
On May 8, 2018, Gaul was found guilty of all charges. He was ultimately sentenced to life in prison without the possibility of parole for 51 years.
He is serving his sentence at the Northwest Correctional Complex in Tiptonville, Tennessee, with an estimated release date of January 27, 2075.
For Emma’s family, the tragedy remains about more than a criminal conviction. Her mother has spoken about trying to create a “new normal” while keeping her daughter’s memory alive, including through a scholarship established in Emma’s honor.
Emma’s story continues to serve as a devastating reminder of how controlling behavior, threats and an inability to accept a breakup can escalate into deadly violence.
