Neither alcohol nor drug use was apparent at the Dalton house Monday night, where two brothers fought and one was fatally stabbed, Palo Alto police Sgt. Sandra Brown said today.
Now there is only grief.
The mother, listed in the phone book as Patricia Dalton, declined to comment.
"I'm just too upset to even talk," she said.
A neighbor, also upset, said she had lived near the Daltons for 45 years and called them good neighbors.
Brown said she did not know if James or John Dalton had a criminal record, but said it was not an address familiar to the police. Toxicology tests have not been completed, she said.
Around 6:20 p.m. Monday, John Dalton, 53, was stabbed at his house on Victoria Place, a short cul-de-sac off Wilkie Way. He died later that evening.
His brother, James Dalton, 52, who also lived at the house and was unemployed, was arrested on suspicion of murder shortly before 11 p.m.
The ranch-style house is a faded blue. A brick path circles a raised garden bed in the front yard, where three angel statues sit.
A small pickup truck was parked in the driveway and a maroon Cadillac was parked in the street.
When police arrived after their mother called 911, John Dalton was lying in the driveway, bleeding from a wound from a large kitchen knife. He was rushed to Stanford Hospital, where he died shortly before 9 p.m., according to Agent Dan Ryan.
James Dalton, a heavy-set man who is 6 feet 1 inch tall, was still in the house and cooperated with police, Brown said.
