Search warrants filed hours after the Aurora shooting suspect James Holmes received six deliveries from an online ammunition vendor in the weeks before the massacre last July, which left 12 people dead and 58 more wounded, the Associated Press reported.
Holmes is charged with 166 counts of murder, attempted murder, as well as other offensives in connection to the Aurora shootings.
Newly unsealed warrants revealed that Holmes received six deliveries revealed that Holmes got six deliveries of ammunition from online retailer BulkAmmo.com, UPI reported. Police announced that Holmes purchased over 6,000 rounds of ammunition online leading up to the shooting.
In addition to purchasing ammo online, Holmes also purchased two gas canisters and body armor, prosecutors revealed. His weapons included an assault rifle, shotgun and two Glock pistols were bought at local sporting goods stores.
The warrants also show that Holmes received ammo shipments and also several other packages sent to his apartment "on an almost daily basis" in the weeks leading up the shootings, The Denver Post reported.
Police found more than 30 homemade grenades, 10 gallons of gasoline, and improvised explosives devices and trip wires, which were secured from his apartment.
His legal team has opted to have him plead not guilty by reason of insanity. Holmes' lawyers argued Thursday that laws on insanity and the death sentence could potentially keep him from presenting expert testimony about his mental state during the penalty phase of his trial, news reports said.
"If the defendant invokes the not guilty by reason of insanity defense, he will have to submit to a state examination, one which may include interviews, polygraph tests and even tests using narcoanalytic drugs.
The defense team, argued it is unconstitutional to limit expert testimony at a sentencing stage of a capital case.
Prosecutors, however, argue that the laws are fair and their principles have been upheld by appeals courts. They also say it is too early to consider the matter.
The judge said the state has an interest in the right to examine the defendant if he brings up his mental state as an issue; the advisement is currently set for May 31, news reports said. The judge added that he will make a ruling before that advisement.
