TBS Today: Who is Jonah Roper?

A man alleged to have killed his mother Saturday in a brutal stabbing in Berkeley has a documented history of psychiatric problems and violence, according to court records reviewed by The Berkeley Scanner.

Jonah Roper, 36, is alleged to have stabbed Maura Ghizzoni, a 60-year-old midwife and artist, at her Berkeley Hills home in the 900 block of Overlook Road.

On Monday, The Scanner reviewed Roper's extensive criminal court file and found a history of violence and mental illness dating back to at least 2005 when Roper was just 18.

We reviewed hundreds of pages and uncovered a letter written by Ghizzoni on behalf of her son in 2009. We also found background on Roper's mental health struggles.
