"Mariah isn't upset over the belongings because $50K to her is nothing," said a friend of the "Hero" singer to Radar Online. "But she is upset because she believes that it was not just a random robbery."
Mariah, who was in New York City during the heist, allegedly noted that the robbers, who made off with $50,000 worth of her personal belongings, "had to know she was not in town because Mariah keeps a very private schedule, especially when she is traveling."
The break-in happened at 3 A.M. on Thursday, October 19, with the burglars reportedly using a ladder to get into the singer's bedroom through a window. Oddly enough, the mansion's silent alarms were set off, but the security team didn't discover the heist until 6 or 7 A.M.
"The robbers knew to go in her bedroom window and there are hundreds of windows on her house," the source added. "The fact that the burglars set off the alarms and her security did not respond has made her question her security and she is considering whether or not she is going to replace them all."
Kim Kardashian and Kanye West's home in Bel Air was also targeted by a thief, a year after the TV personality was robbed at gunpoint in Paris. Previous report suggested that the man caught on surveillance camera never entered the house, but he trashed the cars at the end of the driveway. The man, who also targeted the house next door owned by Kathy Griffin, ran off with an iPhone which belonged to the staffer before he was chased off by a guard. No suspects have been arrested.
