Minnesota Man Sentenced to 33 Years for Fatal Stabbing of Wife During Bible Study

Hidden Killers With Tony Brueski | True Crime News & Commentary

Months after pleading guilty to second-degree murder, a Minnesota man has been sentenced to 33 years in state prison for fatally stabbing his wife in front of family members during a Bible study session. Robert Castillo, 40, attacked 41-year-old Corrina Woodhull with a hunting knife on March 21, 2023, at his sister's home in St. Paul.
According to authorities, the violence unfolded shortly after Castillo whispered something to Woodhull, prompting her to shake her head "no." He then drew a hunting knife and stabbed her between 10 and 20 times in the upper body. Family members present at the Bible study tackled and disarmed Castillo until police arrived.
Woodhull was transported to a local hospital but succumbed to her injuries. Witnesses reported that she pleaded for her life during the attack, saying, "Don't let me die."
At Castillo's sentencing on Friday, Woodhull's mother, Linda Castillo, revealed that she found divorce papers in her daughter's car after the murder. "She knew it was time to walk away, and that's why she's dead," Linda said.
Castillo's sister told police that the couple had arrived together for the regular Tuesday night Bible study and had been holding hands and kissing before the attack. Castillo's brother mentioned that the couple had been experiencing marital issues.
Authorities noted that Castillo had an active warrant for his arrest at the time of the stabbing for failing to appear in court on charges related to assaulting a prison guard. His criminal history includes eight prior felony convictions, including an assault charge for allegedly beating the mother of his child with a hammer.
Woodhull was a mother of five and worked at Juel Fairbanks Recovery Services, where she helped others struggling with substance abuse. The organization released a statement mourning her death: "Corrina had so much light, and she spread that light and positivity each and every day to our clients and staff. She leaves behind a legacy here at Juel Fairbanks, and she will be truly missed."
Castillo's attorney asserted that his client was a methamphetamine and heroin user who was in a state of psychosis at the time of the stabbing.
Under the terms of his sentence, Castillo must serve at least two-thirds of his 33-year prison term before he is eligible for release.
