Kassidy Pemberton (left), 14 and Karissa Pemberton, 7, enjoy the backyard of their family's Maryland Heights home Saturday, Sept. 27, 2014. Karissa's older sister Kirstee died in 2004 at age 12 after battling brain cancer. Family members have faced other health issues which mom Kirbi Pemberton believes are related to the nearby West Lake Landfill and to her children attending Rose Acres Elementary, which is also close to the landfill.
