A Montgomery County judge has added another 60 days to a Norristown State Hospital commitment for a man accused of killing three family members in Upper Merion. The judge said 23-year-old Joseph McAndrew Junior (pictured here) is in need of further inpatient care. He is accused of killing his mother, father and brother at their home on Holstein Road in the Gulph Mills section of the township in March of this year. Court documents indicate he had been dealing with mental illness, possibly schizophrenia, prior to the killings. His twin brother James, his 70-year-old father Joseph McAndrew Senior and his 64-year-old mother Susan were stabbed to death with an 18-inch dagger. He faces formal arraignment November 3 on three counts of first degree murder.
