A publicity-shy man who shot to death...

A publicity-shy man who shot to death a knife-wielding teen-ager during a robbery attempt in Chicago has failed to surrender and police believe he may have been deterred by reporters camping on his doorstep. Police say it is unlikely he will be charged. A third party who talked to police on the behalf of the unidentified man said the suspect feared the amount of coverage his case has received because of its parallels to New York’s so-called subway vigilante case. Chicago police have played down any similarity between the Thursday night shooting and the case of Bernhard Goetz, who wounded four teen-agers after one of them asked him for money on a New York subway.
