Robert Castillo pleaded guilty to second-degree murder with intent in the fatal stabbing of his wife, Corrina Woodhull, on March 21, 2023. Court documents say Castillo and his wife went over to Castillo's sister's house for a Bible study. Castillo's sister told police Castillo and his wife were on the couch acting normally; he held her hand and kissed her, then whispered something in her ear. Woodhull then shook her head 'No' and Castillo pulled out a knife and stabbed her about 20 times. Witnesses said that things seemed fine between Castillo and Woodhull, and no one heard what Castillo said to Woodhull before he stabbed her.
