[3][4] Caruso started shooting as part of the Police Athletic League (PAL) at the age of eleven.

She first competed at the USA Shooting National Championships, where she had won four gold medals (2002, 2005–2007), and set numerous records in the air rifle.

[6][7] At the 2004 Summer Olympics in Athens, Caruso narrowly missed out of the final in the women's 10 m air rifle, finishing in ninth place for a score of 396 targets.

She was also part of a six-person tie for the final three slots, but lost in the tie-breaking procedure by comparing the shooters' last series of targets.

[9] Unlike her previous Olympics, she finished only in fifteenth place by two points behind Norway's Kristina Vestveit from the final attempt, for a total score of 395 targets.
