SALINAS (AP) – Prosecutors say they plan to file first-degree murder charges against a woman and teenager in the death of two children found in a California storage locker.

The disclosure came at a news conference Thursday in Monterey County, where authorities believe the children – ages 3 and 6 – were killed.

Prosecutors say they will decide later whether to seek the death penalty.

Police have said the children were killed in a Salinas apartment around Thanksgiving then taken 300 miles to the locker in Redding.

The Associated Press typically does not identify abuse victims; it is not naming the woman and teenager because their relationship to the children is unclear.

The investigation began on Dec. 11 when a 9-year-old girl suffering from neglect and abuse was found near a house in Plumas County, where the woman had recently moved.

The woman and teen were charged with child abuse, torture and mayhem in that incident. Their lawyers have declined comment.
