SANDY — A Sandy woman was robbed at knifepoint by two women, one of whom she knew, and a man who knocked on her door Wednesday, police said.

Around 1:40 p.m., the woman responded to a knock on her door at her home near 8800 S. 280 East. She opened the door to find the three people on her doorstep, said Sandy Police Sgt. Justin Chapman.

One of the suspects, described as a white woman in her 30s wearing a white hat, immediately put a knife to the woman's neck before the trio forced the woman to a safe in her basement, Chapman said. The knife made a "very small, superficial" cut on the woman's neck.

The trio had the woman open the safe and stole cash and jewelry from her before fleeing the home, police said. The group left in a white, "older-model sedan, possibly a Cadillac," Chapman said.

The other suspects were described as a "fairly large woman" in her 40s and a Hispanic man who appeared to be about 45 years old. Police said the woman who was robbed knew one of the suspects by name, "but only as an acquaintance."
