A Texas mother and her boyfriend were gunned down outside their Houston home shortly after dropping their 4-year-old son off at school, allegedly by the woman’s jealous ex-boyfriend, who had reportedly threatened to kill the man just hours earlier.
Dariela Elizabeth Cardona, 29, and Erick Von Gerbitz, 41, were found dead in their driveway Monday morning, October 5, in a shooting that has left two young boys without their mother and a grieving family questioning whether the tragedy could have been prevented.
Police arrested 31-year-old David Elijah Herrera later that day and charged him with capital murder. Court documents allege he confessed to both killings, while investigators believe the attack was motivated by anger over Cardona’s decision to end their relationship and reunite with Von Gerbitz, the father of her youngest son.
According to the Houston Police Department, officers responded to reports of gunfire around 8:15 a.m. at a residence in the 900 block of Lindale Street, just north of Interstate 610. When officers arrived, they discovered Cardona and Von Gerbitz suffering from multiple gunshot wounds. Both were pronounced dead at the scene.
Family members said the couple had just returned from dropping their 4-year-old son off at school when Herrera allegedly confronted them outside the house.
Security footage reviewed by Von Gerbitz’s sister, Lisa Leal, reportedly showed the couple pulling into their driveway and discovering Herrera waiting nearby. When Von Gerbitz told him to leave, Herrera allegedly opened fire, killing both adults before fleeing.
The attack came after weeks of tension following Cardona’s breakup with Herrera, according to relatives. Family members said she had ended the relationship roughly a month earlier and recently reunited with Von Gerbitz, who had moved back to Houston from Amarillo in hopes of rebuilding their family.
But relatives say there had been a frightening warning the night before the killings.
Von Gerbitz’s mother, Blanca Gerbitz, told Houston television station KHOU 11 that her son called her Sunday evening and said Herrera had threatened his life.
During that conversation, she said, her son complained that he had called 911 but officers had not arrived despite several hours passing.
“I called 911 and it’s 11:00 and they never came,” Von Gerbitz reportedly told his mother. “It’s been four hours, and they never came.”
Authorities have not publicly confirmed the details of that alleged emergency call or whether officers responded before Monday’s shooting. The family’s account has nevertheless raised serious questions about what happened during the hours leading up to the couple’s deaths.
Blanca said she had already been worried about her son’s safety, recalling an uneasy feeling when she drove him back to Houston two weeks earlier.
“I’ve had a bad feeling, son, and that’s why I brought you home,” she remembered telling him.
Her fears became reality Monday morning when she learned that both her son and Cardona had been killed.
After the shooting, investigators quickly began searching for Herrera. A witness reportedly saw a vehicle leaving the neighborhood and recorded part of its license plate, giving detectives a crucial lead.
Police used Flock Safety license plate recognition cameras to track a red Ford Fusion believed to be connected to the suspect. The vehicle was eventually located in Liberty County, northeast of Houston, where deputies stopped it and took Herrera into custody.
He was transported back to Harris County and booked into jail on a capital murder charge.
During an initial court appearance, prosecutors presented allegations that Herrera had deliberately shot his former girlfriend and her new partner. A magistrate denied him bond, citing the seriousness of the charges and the alleged confession.
While investigators worked to establish the circumstances surrounding the killings, relatives and neighbors remembered Cardona as a devoted mother who was working hard to build a better future for her children.
She was a hairstylist at a salon in Houston’s Heights neighborhood, where coworkers said she had spent approximately two years developing her career and building relationships with clients.
One former coworker remembered her contagious laugh and warm personality, describing a woman who brought happiness to those around her.
Neighbor Jesus Flores, who had known Cardona’s family for years, recalled how much time and energy she devoted to her sons.
“She loved her sons; she was always taking them out,” Flores told ABC13 Houston. “She just started her business; she was doing hair, she was doing really well. Everything she could do, she did it for them.”
Von Gerbitz was also looking forward to a new beginning. After spending time in Amarillo, he had returned to Houston hoping to restore his relationship with Cardona and spend more time with their young son.
Instead, the couple’s reunion ended in tragedy, leaving their families grieving and two children facing life without their mother.
Investigators are treating the killings as a suspected domestic violence-related crime, and authorities believe jealousy over the couple’s reconciliation may have contributed to the shooting.
The case comes amid continued concern about domestic violence in the Houston area, where law enforcement officials have emphasized the dangers that can arise when threats and controlling behavior escalate after a relationship ends.
Harris County prosecutors have been working with local agencies to strengthen support services for victims and families affected by domestic violence, particularly in cases involving threats from former partners.
For Blanca Gerbitz, the tragedy has left one warning she hopes others will remember.
“Don’t ever underestimate a jealous person,” she said. “Never.”
Herrera remains in the Harris County Jail without bond. His next court appearance is scheduled for November 5, and he is presumed innocent unless proven guilty.
