David Fidel Mora-Rojas, 39, fatally shot his three daughters and a male chaperone at a Sacramento church earlier this week.
It turns out Mora-Rojas had overstayed his visa and was in the US illegally when he killed his daughters and turned the gun on himself and took his own life.
According to ABC News, Mora-Rojas was arrested in Merced County last week on charges of resisting arrest, driving under the influence and assaulting a police officer.
The Daily Mail reported:
The gunman who killed his three daughters and a chaperone who was supervising his visit with his children, before turning the gun on himself and taking his own life in a northern California church this week, was in the United States illegally, immigration officials said Friday.
David Mora, 39, overstayed his visa after entering California from his native Mexico on December 17, 2018, on a non-immigrant visitor visa, U.S. Immigration and Customs Enforcement (ICE) spokeswoman Alethea Smock said.
Smock did not say when his visa expired, but because he overstayed his visa, ICE asked to be notified when he was released from jail last week after he was arrested in Merced County for allegedly assaulting a California Highway Patrol officer.
The shootings at a church in Sacramento occurred Monday during a weekly supervised visitation Mora had with his daughters, aged 13, 10 and nine.
Police have revealed no motive but the confirmation that he was in the country illegally provides a possible reason: Mora may have feared being deported and separated from his children.
