Gregory Terrell is a volunteer violence interrupter in Cleveland, Ohio. He runs a non-profit called and works mostly in the Central neighborhood on Cleveland鈥檚 East Side. Everyone who knows him calls him Tonto.
Cities across the U.S. are trying to reduce gun violence, with many turning to 鈥渧iolence interrupters鈥 like Tonto. They are community members who set out to mediate conflicts before violence escalates.
鈥楤een Going On Since Before I Was Born鈥
The day-to-day of Tonto鈥檚 work involves lots of driving around talking with people in the community.
鈥淚 do this all day, every day all over the city,鈥 Tonto said as he drove through neighborhoods near Cleveland鈥檚 King Kennedy public housing projects on a cold afternoon in February.
Along the way, he stopped and chatted with older men standing outside a supermarket. He checked in with residents of the public housing where he grew up and pointed out the ones where shootings are most frequent.

King Kennedy was built almost half a century ago. Inside Tonto stopped by Shay Perry鈥檚 small, second-floor apartment where she lives with her two young boys.
The public housing complex is a maze of run down apartment buildings, ball fields, a school and social service buildings that covers a few city blocks on the east side of Cleveland.
While her kids play on the floor next to her, Perry says she doesn鈥檛 leave the house much anymore. There are long-standing feuds between King Kennedy and other housing projects in Cleveland, especially Valley View, that can often lead to shootings outside her door.
鈥淭hen the King Kennedy boys will go retaliate in their projects. It will never fail,鈥 Perry said. 鈥淭his has been going on since before I was born and it still happening.鈥
And Perry doesn鈥檛 think it will end anytime soon.
鈥淏ut don鈥檛 nobody speak up for anybody who lives down here, knowing they鈥檙e supposed to be protecting,鈥 Perry said.
This is where Tonto tries to help. The idea is his connections will come in handy after a shooting. He can reach out to people on both sides of the dispute to calm tensions and try to mediate.
鈥淚t depends on what happened,鈥 said Tonto. 鈥淚鈥檓 not going to lose my credibility. But at the same time I鈥檓 not going to allow anybody to just wreak havoc in my community and not make you pay for that s*** either.鈥

He鈥檚 not a police officer but sometimes he鈥檒l share what he learns with the police. So, for instance, Tonto goes to the police if a child or an innocent bystander is killed. But in other cases he won鈥檛.
鈥淐ertain things do happen, some people have personal beefs. I ain鈥檛 got nothing to do with that,鈥 explained Tonto.
He used to work with the city鈥檚 youth violence prevention office, submitted incident reports to City Hall and responded to requests for help from police officers and residents.
Tonto鈥檚 role was to help prevent retaliation. He talked to victims and their families, and connected them with social services.
But a year ago there was a change of leadership in the office and they stopped working with him. Now he鈥檚 out on his own.
鈥淲hy I ain鈥檛 got a contract with the city?鈥 Tonto asked. 鈥淚 could take you to these people and they鈥檒l tell you, 鈥榃hen there鈥檚 a shooting, we call him.鈥欌
The Cure Violence Model
The kind of violence prevention work Tonto does, where the community turns to one of their own for help, .
Daniel Webster, the director of the Johns Hopkins Center for Gun Policy and Research, has studied work like Tonto鈥檚, .
According to Webster, the most effective programs all have one thing in common.
鈥淭hey鈥檙e really focused on risk,鈥 said Webster. 鈥淭hey鈥檙e focused on the neighborhoods with the highest rates of gun violence and they鈥檙e focused on the individuals at the greatest risk within those neighborhoods.鈥
The gold standard of this sort of work is , an organization founded by an infectious disease researcher named Gary Slutkin.
His idea was to treat gun violence like a public health epidemic by identifying at-risk people and stopping the spread of the pathogen.
Since 2010, his model reduced gun injuries 50 percent in one Brooklyn neighborhood. In the South Bronx, there was a 37 percent reduction.
But Cure Violence is a more formal approach than the work Tonto does.
鈥淣ew York has had more services and more coordinated efforts to try to change the lives of individuals they鈥檙e engaged with,鈥 Webster said.
But Cure Violence hasn鈥檛 worked in every situation. Webster and his colleagues published a study last year on outreach programs in Baltimore that use the Cure Violence model.
They found a reduction in homicides in several neighborhoods, with one seeing a 54 percent drop in murders in 20 months. But one neighborhood actually .
Webster鈥檚 research has found that success is more likely in neighborhoods with certain characteristics, like places with a history of organizing and a population that isn鈥檛 transient. And all of this requires investment, from the community, and from state and local officials.
Investment In Cleveland
In Cleveland, a group called Cleveland Peacemakers Alliance is getting resources from the city and foundations. The group has 17 full-time staff and a budget of about a million dollars.
Unlike the Cure Violence model, which is run out of a city鈥檚 health department, the Peacemakers is run out of the Cleveland Boys & Girls Club.
The Peacemakers staff follows the progress of people they meet through street outreach. And instead of focusing their efforts on one neighborhood at a time as Cure Violence does, they have interrupters working in different parts of Cleveland.
Peacemakers executive director, Sharyna Cloud, said the decision not to use the Cure Violence model goes back to her organization鈥檚 founding, almost 15 years ago.
As its name indicates, Peacemakers Alliance was meant to gather all the groups already doing violence prevention work in Cleveland. Groups like Tonto鈥檚. But that idea never took hold.
They resurrected the group in 2011 and Cloud took over in 2016.
When Cloud took over, the workers were already scattered around the city and the Boys & Girls Clubs of Cleveland had taken over.
It was then that they considered using Cure Violence strategies, even visiting Chicago to study how it worked there. But in the end, decided against it.
鈥淚t would have meant to pull out those workers who were working in other districts, if we had looked at other data to see what neighborhood was exactly the highest need,鈥 Cloud said. 鈥淪o then the question became, 鈥榃hat happens to all the other neighborhoods?鈥欌

Hospital-based Intervention
Maryum Patterson is a violence interrupter with the Peacemakers. She has an office at Cleveland鈥檚 University Hospitals near the trauma wing.
An incident at the hospital in February proved how useful a full-time violence interrupter can be. After a robbery at a convenience store, the store owner and the suspect were taken to the hospital. The lobby of the hospital filled up with their families, many of whom Patterson knew.
So she started relaying messages from the treatment area back to the family. Some got angry and wanted to retaliate.
鈥淚 had to stand in front of the door [to stop them] and then I summoned assistance from the police,鈥 said Patterson.
Today, Patterson is one of two interrupters the Peacemakers has in the city鈥檚 hospitals.
But much of the city remains beyond their reach.
Tonto says he鈥檚 working on creating a coalition of neighborhood groups that aren鈥檛 working with the Peacemakers.
But so far it鈥檚 just a plan.
