Urubuga Rugali.com rwashoboye kubona raporo yakozwe n’ abahanga bo muri Amerika mu kumenya niba amafoto ari impimbano bakaba bemeje ibyo abenshi twaketse ko amafoto ya Diane Rwigara bayatekinitse.
Radiyo Itahuka yohereje amafoto ya Diane Shima Rwigara muri Cyber Crime Investigation none bakaba bashimangiye ko amafoto ye yatekinitswe bakoresheje Photoshop. Dore iyo raporo hasi nkuko yatugezeho:
