The voices were described as "demons" by law enforcement sources.

Those who knew suspect Nikolas Cruz described him as a troubled teen who was largely alone in the world. An attorney for the family who had taken Cruz in after his adoptive mother died said he was "depressed" following her death but had been going to therapy, while a student who participated in Junior ROTC with Cruz described him as a "psycho" who was enthusiastic about weapons.

Cruz was apprehended by authorities more than an hour after he was dropped off on campus by an Uber, Broward County Sheriff Scott Israel said in a press conference Thursday.

After Cruz was apprehended and read his Miranda rights, he allegedly stated to authorities that he was the gunman who entered the school with an AR-15-style rifle and began shooting students he saw in the hallways and on school grounds, according to a probable cause affidavit from the Broward County Sheriff's Office. He also allegedly stated that he brought additional loaded magazines to campus and kept them hidden in a backpack until he got there and began the attack, the affidavit states.

Broward Health hospitals received 17 patients after Wednesday's shooting at Marjory Stoneman Douglas High School in Parkland. As of Friday morning, those hospitals had one patient in critical condition, seven patients in fair condition and one patient in good condition, according to a statement from Broward Health.

Cruz attended Marjory Stoneman Douglas High School from Jan. 13, 2016, to Feb. 8, 2017, according to school records obtained by ABC Miami affiliate WPLG.

Cruz bought the weapon allegedly used in the crime just three days after his last day attending the school, on Feb. 11, and picked it up one week later on Feb. 18, 2017, following a background check, an attorney for the gun store owner said in a statement.

An assault involving Cruz occurred on Jan. 19, 2017, the records show. On that same day, he was suspended for one day and a threat assessment was ordered for him. He had been suspended for two days one month earlier. It is unclear what the result of the threat assessment was or whether one was even conducted.

School officials declined to answer questions about Cruz's record, citing privacy rules.
