Heather Lauren Downs, a 50-year-old computer scientist from Palo Alto, California, tragically died on December 13, 2017, in what authorities have determined to be a murder-suicide. Downs was found dead alongside her partner, Selene Kalista Makarios, 57, at their home on Tuscany Court. The police were alerted to the scene after neighbors reported hearing gunshots. Upon arrival, officers discovered both women had succumbed to gunshot wounds.
The San Mateo County Coroner's Office later confirmed the identities of the deceased and the nature of their deaths.
Downs and Makarios were both highly accomplished in their field, having worked together at the Portola Group, a wealth management firm, where they contributed to several patents. They were also domestic partners for about 20 years. Downs was known for her brilliance in programming, while Makarios was recognized for her extensive expertise in computer science, including her work as a research associate at Stanford University. Despite their professional achievements, the circumstances leading to the tragic event remain unclear.
The investigation revealed that Makarios shot Downs before turning the gun on herself. This conclusion was supported by the absence of any signs of struggle or prior incidents of domestic violence reported at their residence. The motive behind Makarios' actions remains unknown, leaving family and friends in shock. Downs' sister, Amy, expressed disbelief, noting that there were no indications of any issues when she last spoke with Heather.
The case did not result in any arrests or further legal actions, as the primary suspect, Makarios, was also deceased. The police investigation focused on understanding the dynamics of their relationship and any potential stressors that could have led to the murder-suicide. However, no definitive answers have been provided, and the incident remains a tragic mystery for those who knew the couple. The local community, particularly those involved in the Palo Alto and Menlo-Atherton Adult Soccer Leagues where Downs was an active member, mourned the loss of two talented and beloved individuals.
