Policeman kills himself after shooting another cop outside a Starbucks... and it may have been over the mysterious relationship between the shooter's wife and target

A police officer who shot another cop before killing himself may have been driven to the shootings by a 'relationship' between his victim and his wife.

Hamilton police Sgt. Kenneth Nagy, 43, shot Beverly police Officer Jason Lantych, 36, in the leg and wrist on Friday outside a busy Starbucks, before returning to the scene a few hours later to commit suicide with a gunshot to the head.

District Attorney Jonathan Blodgett said that his office will investigate the relationship between Lantych, who is recovering in hospital and the shooter's wife, Katie Nagy, 32, who works as a victim advocate in the Beverly Police Department's domestic violence unit.
