What is Turquoise Alert and why is it issued for 21-year-old Isabella Comas

A Turquoise Alert has been activated by Arizona authorities on Tuesday evening as the investigation into a missing 21-year-old female from Avondale revealed some inexplicable and possibly hazardous factors associated with the incident.

This type of alert is activated by the Arizona Department of Public Safety at the request of local police departments when all local leads are exhausted, and public assistance is a crucial determinant of a safe recovery.Isabella Comas is the missing woman who left a friend’s house but failed to show up at her destination address. Her absence from any working hours, a lack of communication, and an unaccompanied retrieval of her cell phone are some factors that led this case to go beyond local authorities' control.

What is a Turquoise Alert and why was it issued

The Turquoise Alert program is a notification system designed to quickly inform the public when an endangered person, including tribal members under the age of 65, goes missing and meets specific activation criteria. Alerts are issued and coordinated using multiple resources to ensure widespread awareness. The purpose of the Turquoise Alert is to aid in the safe and rapid recovery of the missing individual through efficient communication and information sharing.

This system is also known as “Emily’s Law,” in memory of Emily Pike, a San Carlos Apache Tribal member, to honor her life and legacy. In this case, investigators entered the missing-person report into national databases, issued bulletins and alerts to other agencies, contacted hospitals and jails, tracked mobile phone data, and reached out to friends, family members, and possible alternate residences. After completing these steps, authorities concluded that Comas’ disappearance met all legal criteria for a Turquoise Alert, including the belief that she may be in danger and that sharing information publicly could assist in her recovery.

Legal criteria governing the Turquoise Alert system

Purpose and origins of the Turquoise Alert programme

The Turquoise Alert programme was created to address cases that fall outside the scope of Amber Alerts and Silver Alerts. It is also referred to as Emily’s Law, named in memory of Emily Pike, a San Carlos Apache Tribal member whose disappearance highlighted gaps in existing alert systems. The programme was designed to ensure that missing endangered adults, including tribal members, receive rapid public attention when traditional investigative tools alone are insufficient.

Its goal is simple but critical: to enable faster, broader communication that increases the chances of safe recovery.

Who Isabella Comas is and where she was last seen

21-year-old Isabella Comas lives in Avondale, Arizona. According to descriptions released by officials through the Department of Public Safety, she is approximately 5 feet 3 inches tall and weighs around 110 pounds. She has pink hair and brown eyes, specifics that authorities hope will make her identifiable to the public if she is seen.

At the time she was last known to be travelling, she was wearing a baggy navy-blue shirt and blue trousers featuring a white stripe running down the side.

She may also have been wearing sandals. These are particularly important in missing-person investigations when clothing and physical features often provide the quickest visual confirmation during public sightings.It was determined that the last known location of Comas was on Sunday at approximately 3 pm in Avondale, near the intersection of Van Buren Street and Avondale Boulevard.

She had been with a friend and had told her that she was going off to see her boyfriend, who lives in the vicinity of 91st Avenue and Indian School Road in the city of Phoenix. It should have been a simple and familiar route, but later evidence indicated that she never got there.

The discrepancy between her departure and her vanishing act was a major point of concern because it indicated that she had no plans of going anywhere else either.

Missed work, broken routine, and the vehicle linked to her disappearance

Alarm bells intensified when Comas failed to pick up a friend for work and did not report to her own workplace on Monday. Friends and colleagues stated that this behaviour was out of character. Repeated attempts to contact her by phone were unsuccessful. In missing-person investigations, sudden breaks from routine are treated as serious indicators of distress or danger, especially when combined with total communication silence.

These red flags prompted her friends to report her missing, allowing law enforcement to begin formal investigative procedures.At the time she went missing, Comas was driving a red Hyundai Sonata. The vehicle bears an Arizona licence plate reading 2EA6LW. Police believe the car may provide critical clues about her movements after leaving Avondale. Whether abandoned, parked, or still in motion, sightings of the vehicle could help reconstruct her route and identify locations that investigators may need to search further.

Authorities have urged the public to report any sightings of the car, even if the encounter seemed insignificant at the time.

Phone tracking data reveals movement across multiple locations

It is highly alarming, though, that the mobile phone belonging to Comas was recovered without her. Using tracking devices, the authorities found phone traffic in multiple locations. These locations included Desert Star Park, 86th Drive, and Encanto Boulevard; the vicinity around 89th Avenue, Glendale, and Glendale Avenue; and the vicinity around El Mirage Road, El Mirage, and Butler Drive. Also, the locations where the mobile phone traffic was picked up cover various regions in the metropolitan Phoenix region, which may indicate more than one location over an extended period.

It is alarming, though, that the mobile phone was found without Comas, which could indicate that she may have been parted from her belongings under stressful conditions.
