Greg Relin appeared in War Of The Roses. He was the killer of Natalie Gibecki.
Natalie took a trip to Mexico. While there, she visited one of the sites the non-profit built an orphanage on. When she got there, she found no such orphanage. Greg was embezzling the funds from his own non-profit, and creating fake images to pass off the illusion of building orphanages and schools in Mexico.
Natalie confronted him on his deception, and in anger he strangled her to death.
