On April 25, 2018, Mark Mangaccat, a 31-year-old resident of Daly City, California, was tragically murdered outside his home. The incident occurred as Mangaccat was backing his car into the garage with his fiancée, Thandar Seinn, in the passenger seat. The couple had just returned from the San Francisco International Airport, where Seinn had completed her final shift as a security officer before their planned move to Las Vegas with their young daughter.
As Mangaccat maneuvered the vehicle, a masked gunman approached and fired multiple shots into the car, killing him instantly. Seinn, who was unharmed, witnessed the horrifying event unfold before her eyes.
The investigation quickly revealed that the perpetrator was Kevin Prasad, a 37-year-old airport security worker who had developed an obsessive crush on Seinn. Prasad had repeatedly asked Seinn out, but she had consistently rebuffed his advances. Despite having no prior conflicts with Mangaccat, Prasad's unrequited feelings for Seinn drove him to commit the murder in a desperate attempt to prevent her from moving away. On the day of the murder, Prasad, along with an accomplice named Donavan Rivera, followed the couple to their home. As Mangaccat backed the car into the garage, Prasad approached and fired five to six shots into the vehicle, killing Mangaccat.
Following the murder, Seinn initially had no idea who could have committed such a heinous act. However, she soon recalled Prasad's seemingly innocent crush on her and mentioned it to the homicide detectives. This crucial piece of information led the authorities to Prasad and Rivera. The following day, both men were arrested and charged with first-degree murder. Prasad was also charged with lying in wait and firing into an occupied vehicle. Rivera, who acted as the getaway driver, was also implicated in the crime.
The case proceeded to trial, where Prasad was found guilty on all counts, including first-degree murder. The prosecution argued that Prasad's obsession with Seinn and his desperation to prevent her from leaving drove him to murder Mangaccat. The jury convicted Prasad, and he was sentenced to life in prison without the possibility of parole. Rivera also faced legal consequences for his role in the crime, although the details of his sentencing were not as widely reported.
The tragic death of Mark Mangaccat left a lasting impact on his family and the community. The case highlighted the dangers of unrequited love and obsession, and the lengths to which some individuals might go when driven by such emotions. The successful prosecution of Prasad and Rivera brought some measure of justice to Mangaccat's family, but the loss of a beloved fiancé and father remains a profound tragedy.
