Nearly four years after a deadly armed robbery claimed the life of a beloved Miami business owner, justice may finally be within reach. Edgar Olivas, a 40-year-old Orlando resident, was taken into custody on July 18, 2026, facing serious charges in connection with the October 2021 murder of Walter Castaneda in Miami’s historic Little Havana neighborhood.
The arrest brings renewed attention to a case that shook the tight-knit community when Castaneda, a 62-year-old Boost Mobile store owner, was gunned down while closing his business for the evening. According to Miami-Dade County records, Olivas was booked at the Turner Guilford Knight Correctional Center near Doral shortly before 8:55 a.m. on Friday, facing charges of first-degree murder and armed robbery with a deadly weapon.
The Night That Changed Everything
The tragic events unfolded on the evening of October 1, 2021, at approximately 8:10 p.m. outside 443 NW 12th Avenue in Little Havana. Castaneda had just finished closing his mobile phone store and was pulling down the security shutters when Olivas allegedly ambushed him in what authorities describe as a calculated robbery attempt.
“Let everything go,” Olivas allegedly demanded of Castaneda, according to witness statements included in the arrest warrant.
What happened next would prove fatal. The arrest warrant details that Olivas, who was 36 years old at the time, forcibly took a black bag from Castaneda. However, the store owner was armed with a .38 caliber revolver and attempted to defend himself, firing at his attacker. Olivas reportedly returned fire before fleeing the scene with the stolen property.
Miami Fire Rescue personnel rushed Castaneda to Jackson Memorial Hospital’s renowned Ryder Trauma Center, but medical staff were unable to save him. A physician pronounced the longtime business owner dead, leaving behind a grieving family and a community demanding answers.
A Trail of Digital Evidence
The investigation that ultimately led to Olivas’s arrest spanned multiple jurisdictions and relied heavily on modern technology and inter-agency cooperation. Miami homicide detectives meticulously tracked the suspect’s getaway vehicle, identified as a white 2022 four-door Honda Civic that had been reported stolen just two days after the murder.
The vehicle’s history proved crucial to the investigation. Records indicate the Honda’s owner had rented the car on September 29, 2021, to a woman later identified as Megan Hester-Villalobos. Her connection to the vehicle opened new investigative avenues for detectives working the case.
Key evidence locations identified through the Honda’s GPS tracking system included:
- A motel located at 148 NW 167th Street, near North Miami Beach
- A gas station at 744 NW 12th Avenue in Little Havana
- An apartment complex at 2523 N. Alafaya Trail in Orlando
The investigation received significant support from the Orange County Sheriff’s Office, whose deputies assisted Miami homicide detectives in uncovering video footage of the Honda Civic. This footage had been published on an Instagram account associated with Hester-Villalobos, providing investigators with additional evidence linking the vehicle to individuals connected to the case.
Justice Delayed But Not Denied
The nearly four-year gap between the crime and the arrest underscores the complexity of building a solid case in violent crime investigations. While the delay undoubtedly tested the patience of Castaneda’s loved ones, the thorough investigation appears to have yielded sufficient evidence for prosecutors to move forward with serious charges.
A judge has denied bond for Olivas, meaning he will remain in custody at the Miami-Dade County detention facility as he awaits trial. The charges he faces carry severe penalties under Florida law:
- First-degree murder: potential life imprisonment or capital punishment
- Armed robbery with a deadly weapon: up to life in prison
The case serves as a stark reminder of the dangers faced by small business owners in urban areas, particularly those who work late hours handling cash transactions. Castaneda’s decision to arm himself for protection ultimately could not save his life, but his act of resistance may have helped investigators identify his killer.
For the Little Havana community, which has long been a vibrant cultural hub for Miami’s Latin population, the arrest represents a measure of closure. The neighborhood’s residents have watched and waited as investigators worked to bring Castaneda’s killer to justice, and many will be following the legal proceedings closely in the months ahead.
As the case moves through the Miami-Dade County court system, prosecutors will face the challenge of presenting evidence collected over nearly four years to convince a jury of Olivas’s guilt beyond a reasonable doubt. For Castaneda’s family, the arrest marks the beginning of a new chapter in their long quest for justice.
