A jury has convicted a 32-year-old man in the 2021 slayings of his four children and their grandmother in Southern California.

Germarcus Lamar David was found guilty Tuesday of five counts of first-degree murder and three counts of assault on a child causing death, the Los Angeles County District Attorney's Office said.

The slayings occurred on Nov. 28, 2021, in the family's home in Lancaster, a city in the Antelope Valley high desert north of Los Angeles. The neighborhood had already been decorated for Christmas when the violence broke out, shocking neighbors.

A neighbor told The Associated Press in 2021 that a woman ran back and forth in their front yard that night, screaming, "My babies are gone! They’re all dead!"

The medical examiner identified the children as Namyiah David, 11; Germarcus David Jr., 7; Kaden David, 2; and Noah David, 19 months.

David’s defense attorney, Deputy Public Defender Anna Brief, said Wednesday that she would not comment until after he is sentenced on April 24.

David was a security guard who had posted online about following a good and religious life. He turned himself in to Los Angeles County sheriff’s deputies within minutes of his wife’s arrival at the home.

David had a permit to carry a gun, but it expired in August 2020 and was listed as canceled, according to records from the California Bureau of Security and Investigative Services, which regulates the private security industry.
