Police have charged 36-year-old Shane Walker with murder after his two toddler sons and their mother, Alla Ausheva, were found dead in their Staten Island home hours after he allegedly stumbled out of the house, drunk, and drove away.

After a member of the Air National Guard and her two children were found dead in their Staten Island home on Saturday, the children’s father is facing multiple charges, including murder.

Alla Ausheva, 37, and her two children — 2-year-old Ivan and 3-year-old Elia — were found dead in their home after police responded to a call about an assault in progress, police said on Saturday. They entered the “smoke-filled” house to find a woman and her two children dead inside.

Ausheva was discovered lying face-down on a bed, with anonymous law enforcement sources telling the New York Post that the mother of two had endured severe trauma to the face and head. Her two children were reportedly drowned in the bathtub.

Just hours before Ausheva and the children were found, surveillance cameras captured the children’s father, 36-year-old Shane Walker, leaving the family home seemingly while drunk and getting into his car, the paper reports, citing those same sources. He later crashed into a truck on the Brooklyn-Queens Expressway and was taken in for an evaluation.

Police on Sunday charged Walker with murder, manslaughter, arson, and criminal possession of a weapon, CNN reports.

While some reports indicate that Walker and Ausheva were romantically involved, police said that the nature of their relationship was not immediately clear, though they do believe that he is the children’s father, police said.

Both Ausheva and Walker were in the Air Force and were stationed at Fort Hamilton in Brooklyn, The Post reports.

Ausheva, who was born in Russia, had lived in the United States since winning a green card lottery in 2011, . She joined the New York Army National Guard months later, and became a naturalized citizen in 2012 at a ceremony presided over by former President Barack Obama.

“I always wanted to live here,” she told The Post in the past. “This is really a country where you can pursue your dream and do what you want to do.”

Ausheva moved to the Air National Guard in 2014, where she worked as a logistics planner, the New York National Guard told Fox News.

Police, who are currently investigating the deaths of Ausheva and her children, said that authorities had been called in response to one “domestic incident” at Ausheva’s home in the past, SILive.com reports.

Walker was arrested for assaulting Ausheva in December, prompting her to get a protective order against him, but that order had expired by the time she and her children were found dead, police told The New York Times. The family moved into the two-story house within the past year, but neighbors report that they did not mingle much with others and that Walker was rarely seen, according to the outlet.

Col. Richard Goldenberg, a public affairs officer for the National Guard, offered their condolences in a statement. obtained by The Times.

“The New York National Guard acknowledges the loss of one of our traditional airmen in an apparent criminal homicide,” the statement reads. “Our thoughts and prayers are extended to the families of those involved and the military members who served alongside Airman 1st Class Alla Ausheva.”
