Mason sentenced to almost 22 years for 1999 arson
The Ohio woman who pleaded guilty to setting Agriculture Hall on fire in 1999 was sentenced to almost 22 years in prison Thursday. Marie Mason, 47, of Cincinnati, said she committed the arson with her then-husband Frank Ambrose on New Year’s Eve, 1999. She said the two set the offices of the Agriculture Biotechnology Support Project on fire to protest federally funded research on genetic modification of potatoes.
