( CNN ) -- A West Virginia man has been indicted in the murders of three Alexandria , Virginia , residents over a decade . A grand jury returned a 10-count indictment against Charles Severance , 53 , for the shooting deaths that investigators determined earlier this year were linked to one killer . Ballistic tests showed bullets that killed music teacher Ruthanne Lodato on February 6 , 2014 , are similar to those in two earlier suburban Washington killings , police in Virginia said in March . The slayings alarmed the community located across the Potomac River from the nation 's capital , raising concerns a serial killer might be responsible . Police have said a gunman knocked on Lodato 's door late that morning and began shooting . The 59-year-old woman died , and her mother 's caretaker was seriously wounded . The survivor helped provide a sketch of the suspect . The previous victims were also prominent in the area . Nancy Dunning , once married to Alexandria 's sheriff , was killed in December 2003 ; and Ron Kirby , director of transportation planning at the Metropolitan Washington Council of Governments , was gunned down last November . Alexandria 's Commonwealth Attorney Bryan Porter said he would not seek the death penalty for Severance , although he did not elaborate on that decision . Severance is being held without bond in the Loudoun County , Virginia , jail . CNN 's Deanna Hackney contributed to this report .
