Love's Deadly Triangle: The Texas Cadet Murder (DVD title: Swearing Allegiance) is a 1997 American made-for-television drama film based on the real life murder of Adrianne Jones by Diane Zamora in Texas.

The film stars Holly Marie Combs (as Zamora), David Lipper, Cassidy Rae (as Jones), Dee Wallace, Gary Grubbs, Kurt Fuller, and Joanna Garcia.

The film was adapted from "The Killer Cadets", an article in Texas Monthly by Skip Hollandsworth, and aired on NBC on February 10, 1997.

It revolves around two best friends who turn out to be soul mates and who swear to stay together forever and ever, even to the point where Graham's apparently confessed infidelity leads to the couple's murder of the girl with whom he purportedly cheated.
