On Monday, charges were formally dismissed against Leslie Merritt Jr. at the request of prosecutors after one of their own experts had questioned the ballistics evidence that formed the foundation of the case.
Authorities previously said they used ballistic tests to tie Merritt to four of the 11 shootings, but Merritt's lawyers have recently argued that ballistic tests cast doubt on the claim their client was behind the attacks.
Merritt's lawyers said phone records and accounts from family members showed that Merritt wasn't near the scene of the shootings.
Prosecutors have cast doubt on the alibi claim by saying Merritt's fiancee told investigators that she wasn't sure about his whereabouts.
A judge has barred several documents in the case from public release, including a filing that led to Merritt leaving jail.
