First go to http://news.google.com/newspapers then scroll down to the Vindicator and here you will have a lot of choices but you want the Youngstown Vindicator (the plain Vindicator is only from 1984 on)

Then you choose 1957 or whatever the year you want is, You should be able to find Roosevelt in the obits on the date or the day after, then you can work to the news article when you find the date of the attack (if it isn't the day he died) I thought I would try and google Roosevelt and found this, for his son?
YOUNGSTOWN – Services will be held Monday, Oct. 21, at 11 a.m. at the Shiloh Baptist Church, Campbell, for Mr. Michael “Mickey” Eugene Walker, 58, who transitioned from time into eternity on Sunday, Oct. 13, after an extended illness.
