“The evidence indicates that Ms. Ortiz’s life was taken in a violent domestic attack.  This is a tragedy as children are now left without a mother and have a father who will be charged with her murder if he survives,” said District Attorney Rollins in a statement.  “My heart goes out to these children and this family that is forced to endure tragedy and profound grief during the holiday season.  My office will be available and at their sides to provide the support and resources they may need during this long process.”
