FORT WAYNE, Ind. (WANE) The charges against three men arrested in connection to the August 2015 shooting death of 17-year-old Alonna Allison outside a house party have been dropped.

The Allen County Prosecutor’s Office confirmed to NewsChannel 15 on Tuesday that felony Criminal Recklessness charges against Joshua Smiley, Darrion Bright and Javaris Travier were dismissed. Leroy Allison, Alonna’s father, told NewsChannel 15 that prosecutors struggled to get witnesses to testify.

The prosecutor’s office said three witnesses came forward, but now all cannot be located, have fled town or are not cooperating. However, she says this case isn’t over with. She can bring charges against people in this case at a later time. Prosecutor Karen Richards said hundreds of gunshots were fired that August night and six guns were recovered. She believes possibly 100 people were there. She needs others from that night to come forward.

Allison was shot and killed during a shootout between rival gangs in August 2015. She was attending a gathering at a home in the 2500 block of Schaper Drive when the two groups began shooting.

According to probable cause affidavits, Smiley, Bright and Travier were all identified by witnesses at the party as the shooters. It’s not clear who fired the shot that killed Allison, however.

During an interview with police, Smiley said he was at the party but denied shooting a gun, his affidavit said. Affidavits for Bright and Travier did not indicate they were interviewed by police.

Leroy Allison told NewsChannel 15 after the August 2016 arrests that the charges brought some closure to his family.

Richards called Alonna a “truly innocent victim.”
