The second floor deck collapsed at a home on 100 block of Fantasia Drive at around 9:10 p.m. Saturday night.
The injured people, ranging in age from 14 to 60, were taken to Christiana Hospital for various injures, including some compound fractures.
The wooden deck fell approximately 10 feet during a birthday party that was being held at the home.
McClode also said investigators found problems with the deck's construction. For example, the legs supporting the deck should have been sunk into the ground and had concrete poured around them, but in this instance the legs were standing on a concrete pad.
The son of the homeowner spoke to Action News Monday and said there were 12 to 15 people on the deck at the time it collapsed and there were no warning signs.
He says his parents purchased the home about four years ago and the deck was there when they bought the home.
His mother is still hospitalized today as doctors determine whether she will need surgery.
