A San Francisco investment firm VP who has been described as a mentally ill anti-vaxxer obsessed with government mind control killed his nine-year-old son and then himself last week amid a legal battle with the boy’s mother over his vaccinations and health care.
Police officers performing a welfare check found Stephen O’Loughlin, 49, and his son, Pierce, dead from gunshot wounds inside the O’Loughlin’s apartment in the 3800 block of Scott Street in San Francisco’s Marina District on Wednesday evening
Officers were performing the welfare check at the request of the boy’s mother. She called the police after learning that her son had failed to show up for class at his private Catholic school. 

Police are investigating the deaths as a murder-suicide.
O’Loughlin and his ex-wife, Lesley Hu, executive vice president at a cargo container supplier, had been locked in a bitter custody battle that revolved around their son’s health care.
Lesley Hu’s attorney, Lorie Nachlis, claimed that her her ex-husband, Stephen O’Loughlin, suffered from untreated mental illness, which made him paranoid about vaccinations and obsessed with his son’s health. 
The San Francisco power couple divorced in 2016, and Hu was seeking sole custody of their son so that she could make medical decisions on his behalf without interference from her ex-husband.
O’Loughlin had given his consent to have Pierce vaccinated on Tuesday, a day before their deaths. A trial concerning the custody battle was set to take place in March, reported San Francisco Chronicle.  
A lawyer for Pierce’s mother, Lesley Hu  said O’Loughlin suffered from untreated mental illness that caused him to become obsessed with the boy’s health

According to court records from last September, Hu wrote that O’Loughlin joined a ‘new-age, self-help group’ in 2012 and became convinced that the government was using mind-control on Americans.
O’Loughlin had refused to allow his son to be vaccinated from a young age, claiming that Pierce was vaccine-injured and had suffered serious side effects as a result of receiving shots as a baby. 
Hu, however, denied her ex-husband’s claims and argued that Pierce’s doctors strongly recommended that he be fully vaccinated.    
‘[O’Loughlin’s] stance on vaccinations has taken on a cult-like tone,’ Hu alleged.
The mother also claimed that her ex-husband had become so consumed with their son’s health that he would videotape his breathing several times a day ‘to document a stuffy nose.’ 

Nachlis, Hu’s attorney, pushed back against the narrative that Pierce was killed over his parents’ feud over vaccinations or a stuffy nose, arguing that he carried out the murder-suicide because he felt he was losing control. 
‘He punished Leslie with the ultimate act of violence, killing her child, and she will suffer as I believe was intended for the rest of her life,’ Nachlis said. 
While they were married, O’Loughlin and Hu were heavily involved in San Francisco’s cultural life and helped organize various events.  According to his LinkedIn page, O’Loughlin served as regional vice president at LoCorr Funds, an investment management company.
His ex-wife, Lesley Hu,had only recently been promoted to executive vice president at Waterfront Global, a container supplier where she has worked for more than 15 years.
