Hale, a member of the Pagans Motorcycle Club, was shot three times in the chest from a department-issued .40-caliber handgun after receiving two shocks from electronic Tasers, which caused him to "speak gibberish," witnesses said.
Two children -- ages 4 and 11 -- were sitting on the steps of the house, about three feet away, when gunfire erupted.
Reports on whether Hale was armed or threatened police have evolved.
Master Sgt. Steven Elliott, Wilmington police spokesman, said Tuesday that "there were two items there that were considered weapons, but I haven't been able to confirm whether they were law enforcement or belonged to the suspect."
Asked Tuesday if Hale -- whose hands police said were in his pockets -- ever threatened the officers, Elliott said: "In a sense, when he did not comply with their commands."Elliott said Wednesday a switch-blade knife and "suspected pepper spray derivative" were found in Hale's front pants pockets.
Elliott would not say whether charges were pending against Hale or why officers tried to arrest him.
"I would respectfully defer to the state police," he said.
State Police Superintendent Col. Thomas MacLeish did not return numerous calls or e-mails seeking comments for this article.
The search and subsequent shooting are part of a statewide crackdown Pagans say is targeting the club. Delaware State Police would not comment.
Public records filed with the court Wednesday show the reasons for the search warrant that preceded Hale's death.
