Angel Initiative Pilot Program

The primary goal of the Phoenix Police Department is to help the community. With that goal in mind we are willing to explore various programs and options, some of which may be considered non-traditional. Drug use and addiction is a serious problem with a known link to crimes such as burglary, theft, prostitution, and other kinds of abuse. Drug addiction is a disease with a stigma attached. Addicts often desperately want help with their addiction but aren't sure how to get it and are afraid to admit to anyone, let alone the police, that they are users. 

The Maryvale Estrella Mountain Precinct has a high incidence of drug overdoses and it also has the highest rate of child removal by the Arizona Department of Child Safety. The number one reason for these removals is drug use in the home. We want to keep families together and reduce the risk of these children growing up to become criminals themselves. By offering help we can reduce the stigma, reduce the crime rate, reduce the child removal rate, and reduce the overdose rate. 

With that in mind Commander Sean P. Connolly of the Maryvale Estrella Mountain Precinct, in cooperation with Maricopa County Attorney Bill Montgomery, District 7 Councilman Michael Nowakowski, and City officials, will be piloting the Arizona Angel Initiative in West Phoenix with the Phoenix Police Department, Maryvale-Estrella Precinct.

The Arizona Angel Initiative allows citizens to walk into a police precinct, turn in their drugs and request treatment without fear of prosecution.

To participate the following criteria must be met.
  • Must be an adult age 18 or older.
  • Must live in the Maryvale area.
  • Must be willing and able to follow staff directions.
  • Must have a valid Identification Card.
  • Must agree to abide by all rules and refrain from engaging in illegal and/or inappropriate activity.
  • Must be willing to go to detox and obtain medical clearance, if detox is required.
  • Be physically and mentally able to self-manage personal hygiene and self-care within a non-medical, non-psychiatric facility.
  • Not be a fugitive from justice or have any prior or pending charges for crimes involving violence, arson, sexual offenses, children, or the elderly.
If you meet the above criteria and would like to participate in the Angel Initiative, all you need to do is show up at the Maryvale-Estrella Precinct with a valid State I.D., between the hours of 7 a.m. and 4 p.m., turn in your drugs and request treatment. Although it is preferred that you arrange care for your children while you get help, the Angel will find caregivers who will take them in while you get help and in some cases, you may be able to take your children with you.

The Maryvale-Estrella Precinct is located at:
6180 W. Encanto Blvd. 
Phoenix, AZ 85035

Community members and substance abuse providers can also help the program in various ways. Please visit the web site below to find out how you can become an Angel.
