William H. Spengler Jr. was convicted of first-degree manslaughter in 1981 for beating his 92-year-old grandmother Rose Spengler to death

(NEWSER) – Police have identified the man who this morning fatally shot two firefighters responding to the blaze he set in his own house as 62-year-old William H. Spengler Jr., reports the Rochester Democrat and Chronicle.
Spengler was convicted of first-degree manslaughter in 1981 for beating his 92-year-old grandmother Rose Spengler to death with a hammer; he served 17 years in prison and had an "uneventful" parole that ended in 2006.

He added that mental health issues were probably involved.
