A transient has been charged with stabbing three other homeless people, killing one, last week in Pomona, the Los Angeles County District Attorney’s Office announced today.

Jose Alfredo Mancinas (dob 7/16/97) of Pomona faces one count of premeditated murder and two counts of premeditated attempted murder in case KA120419, which was filed yesterday. The charges include allegations that he used a deadly and dangerous weapon, a knife, and inflicted great bodily injury.

He is expected to be arraigned today in Department N of the Los Angeles County Superior Court, Pomona Branch.

On the evening of March 8, Mancinas allegedly stabbed a man in the face at a bus stop at East Holt and North Towne avenues. The victim was injured but was able to flee, prosecutors said.

The following day, the defendant is accused of attacking a man and a woman in the 1200 block of East Mission Avenue near a homeless shelter where all three had been staying. Mancinas allegedly stabbed 49-year-old Stacy Lynn Castillo multiple times, killing her, prosecutors said.

The male victim was stabbed in the throat but ran away and was treated for his injuries.

Police officers responding to the scene saw Mancinas walking away and arrested him.

He faces a possible maximum penalty of 64 years to life in state prison if convicted as charged. Prosecutors are requesting bail be set at $4.12 million.

Deputy District Attorney Cesar Rodriguez is prosecuting the case.

The case remains under investigation by the Pomona Police Department.
