As it happens, the case above involved a portable radio that had been illegally altered. The expert hams determined that one radio made all of those interfering transmissions. Then when the offender was caught, they identified his radio as the one used to commit the interference. This particular group of hams may assist police in perhaps 15 cases a month statewide. Perhaps that's why they did not respond when I asked for an interview.
Most cases involve accidental interference.
This case was not easily resolved. At one point, they tracked the offender for 24 hours as he kept moving. They made a computer log of the interfering transmissions by frequency, time of day, location to see if a pattern developed. Once they developed enough information for a probable identification of the offender, they turned it over to Lt. James Cetran, Commander of the Detective Division of Wethersfield Police Department.
