Thirty two days after 84-year-oldNancy Guthrie vanishedfrom her Tucson home, investigators are still struggling to explain what exactly happened inside the quiet desert property. With few clear answers and a puzzling trail of clues, some experts are now exploring a disturbing possibility.

The South American Theft Group, often referred to by the acronym SATG, is a loosely organised network of burglars believed to originate from countries including Chile, Colombia, Peru and Venezuela. According to retired FBI agents, membersoftenenter the United States on tourist visas and then overstay while carrying out organised burglary operations.

Their targets are usually wealthy neighbourhoods and expensive homes. Investigators say these crews frequently conduct detailedsurveillancebefore striking, sometimes studying properties for days or even weeks. They often use rental vehicles, fake identification documents and multiple burner phones to avoid detection.

SATG crews also rely heavily on technology. Experts say they commonly use encrypted messaging apps to communicate and sometimes carry radio jamming devices designed to interfere with home security systems and surveillance cameras.

In recent years, authorities have linked similar burglary rings to a wave of crimes across the United States, including break ins at the homes of professional athletes and business executives. In one case connected to the burglary of a football star's home, suspects were arrested after allegedly stealing around $300,000 in luxury goods.

Some elements of the Guthrie case appear to match patterns previously associated with SATG operations. Experts note that the home sits in a relatively quiet area with open land and walking trails nearby. Such locations can provide easy escape routes and hidden vantage points for surveillance.

Investigators also believe the suspect may have visited the property more than once before the crime. Images from adoorbell cameraappear to show the same individual on different occasions, which could suggest the home was being studied in advance.

Burglars linked to SATG operations are known to favour homes with multiple entry points, particularly sliding glass doors and windows. Reports from the investigation indicate that Guthrie's property had several possible access points that could have been used during a break in.

The groups typically focus on items that are easy to sell quickly, such as jewellery, watches and designer accessories. Experts say older homeowners may also become targets because they are perceived as less able to resist during a burglary.

Despite these similarities, the SATG explanation does not neatly solve the mystery. Former investigators point out that these burglary crews usually avoid homes that are occupied. Entering a residence while someone is inside dramatically increases the risk of confrontation or violence.
