Background
Thomas McIlvane was 31 years old and of nearby Oak Park. Mark Mitchell, 28, who once worked with Mr. McIlvane and said they had served together in the Marines, said Mr. McIlvane was discharged dishonorably after running over a car with a tank.
After several running disputes with postal managers, Mr. McIlvane was dismissed from the Postal Service for what postal officials termed “insubordination.” He had been previously suspended for getting into altercations with postal customers on his route. Postal officials acknowledged that they had been aware of Mr. McIlvane's threats but said there was little they could do. “This is a mail-processing facility; it is impossible to keep it locked up tight,” said Art van de Putte, a postal inspector.
Mr. McIlvane appealed the dismissal through a union grievance procedure, and a postal official said he lost an arbitration hearing six days before the incident, which made the dismissal final. Charles Withers, a shop steward for the letter carrier's union, said the arbitration hearing loss made the dismissal final. He had been previously suspended once for fighting with customers on his route.
Mr. Mitchell described Mr. McIlvane as being a martial arts enthusiast with a black belt in kick-boxing who had competed on television.
He was known to police. Oakland County officials a year ago had issued Mr. McIlvane a permit to carry a concealed weapon, but the permit was revoked May 7 after the Oak Park police became concerned the man was mentally unstable during a police investigation into complaints that he was being threatened. The police in nearby Southfield said Mr. McIlvane recently had been acquitted of a charge of making threats over the telephone. Records show he bought a rifle three years ago and also owned a .357-caliber pistol.
He was described as having several times threatened violence if he was not reinstated. Edward Fink, 38, a postal clerk, said: “A lot of people thought he had a short fuse.”
The case context also included other prior incidents at post offices in recent years: in August 1986, a part-time letter carrier in Edmond, Okla., killed 14 people in the post office before taking his own life; in December 1988, a postal worker in New Orleans shot and wounded three people; in August 1989, a postal worker shot his wife to death in Escondido, Calif., then drove to the Orange Glenn post office and shot and killed two colleagues and wounded another before killing himself; and in October, a postal worker who had been let go killed a former supervisor and her fiance in Wayne, N.J., then went to the nearby Ridgewood post office, where he killed two mail handlers.
In narrative material associated with the case, it was said that a month after lethal postal worker Joseph Harris rampaged through his Ridgewood post office, Thomas McIlvane express mailed himself into oblivion. It was also stated that McIlvane was a “champion kick boxer with a black belt in karate,” that he was fired a year before for cursing at his supervisor as well as threatening other clerks and fighting with customers, and that he repeatedly warned he would make Pat Sherrill's massacre at Edmond look like “Disneyland.” It was also stated that after Harris' rampage in Ridgewood, one of the supervisors most hated by McIlvaine got very nervous and called the post-office security division in Detroit to ask for protection, but the request was denied.
The offence
On Thursday morning, Thomas McIlvane walked into a regional postal center and opened fire with a sawed-off .22-caliber rifle. The authorities said he killed three workers and wounded six. Three other workers were injured while trying to escape by jumping out windows of the two-story building during the shooting spree.
The police estimated the shooting spree lasted five or six minutes. After the rampage, Thomas McIlvane turned the weapon on himself and was fatally wounded.
The weapon he used was described as a Ruger semiautomatic carbine he bought at a local gun store. Don Higgerson, an agent for the Bureau of Alcohol, Tobacco and Firearms, said the barrel may have been sawed off to make the weapon easy to conceal.
A man dressed in a postal uniform who declined to identify himself said he saw Mr. McIlvane come into a large room where letters are sorted, start shooting, and then leave the room with a coat draped over the rifle. It was said that Mr. McIlvane walked in through an unlocked entrance used by employees.
A woman who worked on the loading dock said she had been told a month ago by supervisors to “keep Tom McIlvane out if he showed up.”
In additional narrative material, it was stated that on November 14, 1991, the day after his reinstatement was denied, McIlvaine returned to his former post office in Royal Oak with a sawed-off Ruger .22-caliber semiautomatic hidden under his raincoat and “wasted four supervisors,” among them the poor man who requested protection, and wounded five others. After his “ten minutes” of inflicting terror, the narrative states that McIlvane ended his rampage by stamping a bullet through his head and that he lingered in a coma for a day before dying.
In that same narrative, Thomas McIlvane was quoted threatening: “you had better not turn your head because you'll be dead! I'm going to get you!”

Aftermath
The authorities described the postal service center, which processes mail for four counties, becoming a scene of pandemonium when the shots rang out, as more than 160 frightened workers sought to barricade themselves in offices or escape through exits and windows.

In narrative material connected to the case, it was said that workers planned escape routes and feared giving their names because of friction between workers and supervisors during the past two years. Edward Fink said: “Management pushes, pushes and pushes and doesn't know when to quit.” He added: “They don't know when someone is going to break.”
Dan Chestnutt, 37, said: “They pushed the wrong guy too far.”
The narrative also stated that Mr. Mitchell acknowledged he, himself, was recently acquitted on a charge of threatening a postal supervisor with a knife.
Senator Carl Levin and Representative Sander M. Levin agreed to take up complaints from customers and employees of the service center with the Postal Service.
In narrative material, it was stated that Thomas McIlvane repeatedly threatened that if he was not reinstated he would make Pat Sherrill’s massacre at Edmond look like “Disneyland,” and that other descriptions used included “a tea party” and “a picnic.” It also stated he “continuously made threating calls to his supervisors (who reported them to police, who did nothing).” It further stated: “Another postman gone mad. This time in Royal Oak, Michigan.”
Other details
