The first three victims were killed within 11 days in October. Days after Mitchell was killed on Oct. 9, the body of 32-year-old Monica Hoffa was found half a mile from where he was killed on Oct. 13. Anthony Naiboa, a 20-year-old man authorities described as having mild autism, was killed Oct. 19 after taking the wrong bus home from work, and the fourth victim, 60-year-old Robert Felton, was fatally shot from behind in the early hours of Nov. 14, according to police.

Tampa residents \"can rest comfortable\" now that a suspected serial killer has been arrested, Tampa Mayor Bob Buckhorn said Wednesday morning on \"GMA.\"
