Eighty-nine rounds were fired from seven guns during a deadly Alabama shooting that killed four young people, according to investigators.
Ednews reports citing NBC news that they said two of the guns were altered to fire automatically, the Montgomery Advertiser reported.
The revelations were made during a bond hearing for three of the six suspects charged over the 15 April shooting in Dadeville.
The shooting erupted at a dance studio during a 16th birthday party.
There were around 50 partygoers in attendance, authorities said, most of whom were teenagers.
The victims were identified as Philstavious Dowdell, 18, Shaunkivia Nicole Smith, 17, Marsiah Emmanuel Collins, 19 and Corbin Dahmontrey Holston, 23. Thirty-two other people were injured, some critically.
