A former Denver-area teacher's aide has been arrested after four people associated with her died between 2008 and 2011 after mixing drugs.
Fifty-year-old Almeda Sullivan, of Centennial, was held without bond Tuesday in Arapahoe County on charges including drug distribution and first-degree murder. Jail records didn't list her lawyer.
Court documents obtained by KUSA-TV in Denver show Sullivan worked as a bus driver and teacher's aide for the Cherry Creek School District from late 2003 to mid-May 2005.
Investigators say 21-year-old Carter Lee Higdon, 19-year-old Sierra Renee Cochran, 28-year-old Lindsey Jo Saidy, and 20-year-old Martynas "Tez" Simanskas all had drug-related deaths after associating with Sullivan.
An arrest affidavit says that after Higdon died in 2011, Sullivan allegedly told investigators she sometimes sold her prescription drugs to survive financially.
