Man accused of fatally shooting wife, in-laws, and 2 young sons at home

ALAMEDA, Calif. (TCN) -- A Northern California man was arrested for allegedly killing five of his family members, including his two sons, ages 6 and 1.

Alameda Police Chief Nishant Joshi said in a press conference that on the evening of July 10, someone called 911 to report their neighbor had been shot on the 400 block of Kitty Hawk Street. Officers arrived and started assisting the injured victim, then found out about additional victims at a residence nearby. Police went to the other house and were met by 54-year-old Shane Killian, who was detained at the scene.

Joshi said four adults and one child were declared deceased, while the 1-year-old was taken to the hospital in critical condition. Alameda Police identified the victims as Killian's wife, father-in-law, mother-in-law, and 6-year-old son. The 1-year-old son died from his injuries on July 15.

The father-in-law was reportedly the victim who sought help at the neighbor's home before he died.

Joshi said officers recovered "multiple" firearms from Killian's house.

The Alameda County District Attorney's Office announced July 12 that Killian was being charged with four counts of murder, one count of attempted murder, corporal injury to a relationship partner, elder or dependent adult abuse, infliction of injury, possession of an assault weapon, and possession of an unconventional pistol.

As of Tuesday, July 16, the district attorney's office has not shared amended charges reflecting the 1-year-old child's death.

Investigators are still working to determine a motive for the shooting.

Joshi said, "This is a tragic and sad incident. These are the actions of a coward."
