MARTINEZ -- The 22-year-old Clayton man accused in the gruesome death of his father was "prone to rage," according to a restraining order the father filed against his son in 2010.
Matthew Wester, 22, was arrested on suspicion of murder March 8 after his father, 61-year-old Richard Wester, was found dead in the family's home in the 400 block of Meadow View Lane, authorities said.
An autopsy performed Monday concluded that Wester died after more than one of his ribs were fractured, causing blood to pool in his chest. The report said the fractures were due to "traumatic injury," but it did not elaborate.
Court papers filed in Contra Costa detail previous attacks by the younger Wester against his father. On March 5, 2010, Matthew Wester allegedly spit in Richard Wester's face, punched and kicked him, destroyed furniture and waved a knife, according to a stay-away order. The son suffers from Asperger's syndrome and was living in a group home at the time, his father wrote in the court filing.
"He wants to live with me, and when I say 'no' it starts," his father wrote. "This happens every time he visits from his group home ... but (it) is increasing in frequency and intensity."
The elder Wester suffered bruises and cuts, according to court papers. The temporary restraining order was filed March 20, 2010, and the court granted the order on June 2. It expired on June 1, 2011, and Wester apparenly did not have it renewed.
Few neighbors live in the unincorporated area of Clayton where Richard Wester was discovered. Meadow Lane is off Marsh Creek Road, and the beginning of the road that leads back to the home is marked only by four white mailboxes and a street sign.
Police responded to the home at about 11 a.m. Friday after a 911 caller said Wester was unconscious and not breathing. Information about who called police was not available Monday.
Detectives arrested Matthew Wester after interviewing him, and he is being held on $1 million bail at the County Jail in Martinez.
Wester denied this newspaper's request for an interview from jail Monday. Calls to Wester's home and to neighbors have not been returned.
