A Massachusetts man has been arrested and extradited to Louisiana to answer to charges regarding sexual assaults of children that allegedly took place in the 1970s.

The man, now 73, formerly lived in Louisiana. He is accused of two counts of aggravated rape, according to a spokesman for the Jefferson Parish Sheriff’s Office (JPSO). The sexual assaults reportedly occurred between 1973 and 1977, when the children were between 2 and 7 years old. One of the children was a boy, the other a girl.

He was arrested in Pittsfield, Massachusetts, where he has been living. Upon his extradition, he was taken to the Jefferson Parish Correctional Center in Gretna and booked. He is being held without bond.

Officials said the alleged crimes occurred at the man’s homes in both Waggaman and Bridge City. He is registered as a sex offender in both Kentucky and Massachusetts and has at least one conviction on his record. That was a possession of child pornography case that involved a 9-year-old and occurred in May 2011.

The JPSO spokesman said there could be additional victims. In an attempt to find more alleged victims or learn more information about this case, the office released photos of the man that were taken in the 1970s.

These are serious charges that have to do with crimes allegedly committed more than 40 years ago. A defense attorney will have questions about this case. What will the purported victims, who are now well over 40, be able to remember and testify to? What kind of physical evidence is there? And, finally, why did it take so long for an arrest to be made?
