A 66-year-old Oro Valley widow said she used Facebook to identify the assailants who forced their way into her home, bound her hands and feet, and stole her jewelry.

On Wednesday, Ursula Pillar told Pima County Superior Court jury that she began to suspect Jacqueline Michelle Carlson might have been involved in the home invasion after speaking with police.

“It occurred to me that it was just impossible that it was a random act,” Pillar said.

Pillar suspected Carlson because the two women were connected to Wellington Curichimba Marin.

Carlson and Marin are on trial in the November 2012 home invasion.

Marin and Pillar had dated for a few years but broke up months before the incident. Carlson and Marin then began seeing each other .

Pillar found a Facebook entry where Carlson had posted photos of her son, who prosecutors say helped in the robbery. Pillar said Carlson hid her face under the hood of a sweatshirt during the home invasion but her son, Anthony White-Giordano, 18, and another teen did not .

White-Giordano pleaded guilty to aggravated assault and testified that Marin talked about robbing Pillar but that his mother was the driving force behind the crime.

White-Giordano said Marin told them where Pillar kept her jewelry and Carlson did most of the planning.

The day of the robbery, a 13-year-old boy knocked on Pillar’s door and told her he was lost and needed to call his mother. Carlson and White-Giordano rushed inside as Pillar let the boy in. The robbers stole jewelry and $200 in cash.

Carlson’s attorney, Bobbi Berry, told the jury she wouldn’t argue her client didn’t commit the crimes. Rather, Berry said , the crimes were not of a lethal or dangerous nature as the prosecution has charged.

Marin’s attorney, Michael Areinoff, told jurors he planned a similar defense.

Areinoff said Pillar was never at risk of physical harm because the intruders never planned to hurt her and that unloaded BB guns were used.
