Officers were called to the house, in the 1700 block of S. Norfolk Street, about an hour later after the robbery. They learned that two suspects, armed with a gun, kicked in the door and went to the woman’s bedroom. The suspects took her Life Alert button, glasses and a necklace with her late husband’s wedding band, according to police.

After searching the home for valuables the pair fled, leaving the victim stranded in bed until her caregiver, Price, arrived the next morning.

Price allegedly set up the robbery with her boyfriend, 26-year-old Andre John McBride of East Palo Alto, and their associate, 25-year-old Donte Demon Jordan of Hayward, police said.

Price was arrested on Oct. 2; McBride was arrested on Oct. 19 in Texas; and Jordan was arrested on Thursday in Hayward, police said.

“A round-the clock investigation led detectives to Louisiana and many Bay Area cities, bringing those responsible to justice,” police said in a statement.

All three were booked at San Mateo County Jail on suspicion of crimes that include first-degree robbery of inhabited dwelling and willful cruelty to the elderly likely to produce great bodily harm or death.
