有罪になるはbe found guiltyが決まり文句です。ワインボトルで撲殺されるのは嫌ですね。
Kaori Mihashi was found guilty of fatally striking her husband with a wine bottle in December 2006 and disposing of his body parts around Tokyo after cutting up the corpse in the couple's condominium in Shibuya Ward.
どういう罰が下されたのでしょうか?
A 33-year-old woman was sentenced Monday to 15 years in prison for killing and dismembering her husband, with the Tokyo District Court finding her liable for the murder despite being in an impaired mental state brought on by years of severe spousal abuse.
spousal abuseは夫からの虐待ということです。find 人 liable for にも有罪となるニュアンスがあります。find guiltyの言いかえと思ってください。liableの場合はforの後に罪となる行為がきますがfind guiltyは前置詞ofの後にその行為がきます。
