Hundreds of fans took part in activities outside the house in Jackson Street over the weekend ahead of Jackson's birthday on Monday.
Thirteen-year-old Paris Jackson told WLS-TV that she enjoyed seeing so many fans at the house when she and her brothers, 14-year-old Prince and 9-year-old Blanket, visited on Saturday.
The Post-Tribune of Merrillville reports that Jackson's father Joe attended activities at the home on Sunday.
The Jackson family moved from Indiana to California in 1969 after the Jackson 5 struck it big. Jackson died in June 2009.
