Texas Rangers arrested four people this week in connection with a murder-for-hire plot spun out of a love triangle.
Delvin Ajair Powell, 38, Kadie Elizabeth Robinson, 28, Robert Samuel Veal, 35, and Ronnie Keith Welborn, 45, were being held at the Collin County jail on Thursday in connection with the murder of 46-year-old Kelli Underwood who was found dead in her home in Princeton on Sept. 20.
