Mesa Mom Re-Arrested After Toddler Found Drugged in 111°F Garage

A Mesa neighbor who is a foster mother says it took 20 to 30 minutes to wake a two-year-old boy after pulling him from a sweltering home garage on July 29, when the temperature in Phoenix hit 111 degrees. The child's mother, 32-year-old Amy Nicole Shellhammer, has now been formally charged with felony child abuse after court documents revealed the toddler had fentanyl, methamphetamine and THC in his system, and after a pattern of alleged neglect and drug use in the home came to light.

According to court documents relayed by KTAR.com, Shellhammer texted her neighbor on July 29 saying she was leaving her toddler in the garage because she felt sick. The neighbor, worried that the space had no air conditioning and was extremely hot, went in and found the boy sleeping inside the unconditioned garage with nobody else home, per court documents relayed by FOX 10 Phoenix. It reportedly took the neighbor 20 to 30 minutes to rouse the child after getting him out of the heat, and a later medical evaluation found fentanyl, methamphetamine and THC in his system, court documents state.

How Police First Found the Toddler's Living Conditions

Mesa police did not learn the full scope of the boy's home environment until responding to an unrelated emergency days later. On August 1, officers were called to a home near Broadway and Lindsay roads after Shellhammer herself dialed 911 to report a fatal drug overdose involving her roommate, who was the child's father, as reported by 12News.

During that investigation, the neighbor reportedly came forward and reported the July 29 garage incident to officers, per court documents cited by FOX 10 Phoenix. Court paperwork indicates Shellhammer allegedly lied to officers about her relationship to the deceased father and hid baggies containing fentanyl, methamphetamine and possible heroin inside a nearby vehicle, 12News reports. Police say Shellhammer admitted she smokes fentanyl, methamphetamine and marijuana ten or more times a day inside the residence, and investigators say that use exposed her son to the drugs.

Witness Describes an Earlier Garage Incident

The July 29 rescue was not the only allegation of the child being left in the garage, according to the dossier's underlying reporting. A witness interviewed by Mesa police described a prior incident on July 19, when Shellhammer allegedly texted her that she had left her son in the garage, prompting the witness to go find the child dehydrated inside the unconditioned space and photograph the scene, per 12News. Those photos were later provided to investigators, according to the same report.

The Arizona heat makes such spaces especially dangerous. Uninsulated attached garages in the Phoenix metro area routinely reach interior temperatures of 120 to 140 degrees during summer heatwaves, running 10 to 25 degrees hotter than the outside air, according to research from Gecko Garage Doors. Uninsulated metal garage doors function as heat sinks that trap that extreme heat, the analysis notes.

A Colorado Protection Order and a Broken Bond

Court records show Shellhammer was already barred from contact with the toddler under a 2025 protection order issued in Montezuma County, Colorado, which was requested by the child's father before his death. The order required her to maintain at least 100 yards of distance from the boy, and Mesa police confirmed with Colorado authorities that it remained active, per 12News. Shellhammer is accused of a misdemeanor count of failure to comply with a court order in connection with that violation.

Following her initial August 1 arrest, Shellhammer was re-arrested by Mesa police on August 17 after prosecutors returned the case for further investigation, this time formally charging her with felony child abuse, drug possession and court order violations, 12News reports. A judge set her bond at $35,000, with restrictions that include a ban on leaving Arizona and a ban on contacting the toddler and other children. The Department of Child Safety took the boy into protective custody on August 1, according to investigators. A preliminary hearing in the case is scheduled for August 27, per court records.

Charges Carry Steep Penalties Under Arizona Law

Under Arizona Revised Statutes § 13-3623, child abuse committed intentionally or knowingly under circumstances likely to produce death or serious physical injury is classified as a Class 2 felony, carrying potential prison sentences of up to 24 years, according to AZ Defenders. The statute explicitly covers placing children in environments containing toxic substances or physical hazards, the firm notes.

The case fits into troubling statewide patterns. Data from the Arizona Child Fatality Review Program shows substance use was a contributing factor in nearly 20% of all child deaths statewide in 2023, according to Arizonans for Children. Separately, child neglect accounts for roughly 75% of all child removals conducted by Arizona's Department of Child Safety, according to Prevent Child Abuse Arizona. It remains unclear whether prosecutors will pursue additional formal charges tied to the alleged hidden drug baggies or evidence tampering uncovered during the August 1 investigation.
