Custodial dad charged with 2nd-degree murder in death of 6-year-old son; what happened to this boy's mother? (Staunton, Virginia)

I did a quick search on this case, and found no article mentioning that the "girlfriend" was the boy's mother. At any rate, she would have been 13 when the boy was born, so that seems unlikely. But I see no mention of the mother anywhere else either. So what happened to her, given that this appears to be a custodial dad?

Dad is identified as STEVEN DECKER.

STAUNTON, VA (NEWSPLEX) -- In a press release Saturday night, the Staunton Police Department says officers have arrested and charged the father of six-year-old Ezra Decker.

Police say 24-year-old Steven Decker has been charged with second-degree murder and felony child neglect.

The charges come after Ezra died at the University of Virginia Medical Center on Wednesday from severe head trauma.

Police have been investigating the death, even though family and friends say Ezra slipped and fell in the shower.

Decker's girlfriend, 19-year-old Brianna Connolly, has also been charged in connection with Ezra's death.

She is facing a felony child neglect charge.

Decker and Connolly are both also charged with possession with intent to distribute marijuana.

They are being held at the Middle River Regional Jail.
