The gang had certain influential connections with local law enforcement, which assisted in their being able to carry out cattle rustling without interference: Bob Beckwith[2] and Wallace Olinger were Deputy Sheriffs for Sheriff William J. Brady, and gang member Bob Olinger was a Deputy US Marshal.
The Regulators included Billy the Kid, Richard "Dick" Brewer, Charlie Bowdre and Doc Scurlock, but numbered some forty riders in all.
What is known for certain is that Seven Rivers member "Dutch Charlie" Kruling was shot and wounded by Regulator George Coe on the morning of April 30.
Some time after this, Seven Rivers gang member Wallace Olinger allowed Frank Coe to escape, giving him a pistol in the process.
Hugh Beckwith, the gang's leader, continued his outlaw life, but was shot and killed while committing the armed robbery of a general store in Presidio, Texas in 1892.
