Those who have watched the NBC true crime Law & Order True Crime: The Menendez Murders likely remember bigs and pieces of their infamous shopping spree — and how it was one of the key points of evidence the prosecution used against the brothers during their trial. 

Four days after they killed their parents, for example, the brothers dropped $15,000 on three Rolex watches that they wore to the funeral the following day. Lyle's bodyguard, Richard Wenskoski, also said that Lyle often jumped out of his limousine to spend an average of $3,000 on miscellaneous clothing and sports apparel.

Avid tennis players, both Erik and Lyle decided to invest in their athletic careers, dropping tens of thousands of dollars on expensive tennis coaches. Mark Heffernan, for example, testified he trained with the brothers for 10 hours a day. Erik, who was more passionate about the sport than Kyle, spent even more on flights abroad for tournaments and competitions.

Oh, and they both bought gorgeous cars following murdering their parents — Lyle dropped $64,000 on a special edition Porsche Carrera, while Erik upgraded his Ford Mustang for a Jeep Wrangler. Then, Lyle bought a restaurant in Princeton, N.J. for the tune of half a million dollars. The brothers' ultimate goal was to buy a luxury condo in the Marina City Club for a cool $900,000.

None of this is even counting the hotel stays, ski trips, and other investments the brothers sought to deem inadmissible in the courts — or the roughly $5.4 million they spent in taxes and lawyer fees for their defense.
