(CNN) Authorities believe a Florida man arrested last weekend is the so-called Pillowcase Rapist and is responsible for a string of notorious South Florida assaults that took place in the 1980s, the Miami-Dade State Attorney's Office announced Thursday.

Robert Eugene Koehler was arrested in Palm Bay, Florida, after new DNA analysis allegedly tied him to a rape in Miami in December 1983, Eleventh Judicial Circuit Court documents show.

But that DNA also matched samples from a number of cases between 1981 to 1986 left by a suspect who became known as the Pillowcase Rapist, Miami-Dade State Attorney Katherine Fernandez Rundle said in a news conference.

The assailant in those cases is believed to have attacked more than 40 women in metropolitan Miami, often concealing his face with a pillowcase, shirt or towel.

In all, authorities have linked Koehler to at least 25 cases, Fernandez Rundle said.
