21-year-old Ahmad Alissa appeared before Judge Thomas Mulhavill in Boulder, Colorado, on Thursday at 8:15 am, according to The Daily Mail.
Prosecutors stated that they were planning to file more charges against Alissa.
Alissa shot and killed 10 people with his recently purchased $900 AR-556 rifle before surrendering to police officers.
Family and friends described the alleged murderer as a loner, paranoid, stupid, and say he has never had a girlfriend.
Alissa was wearing his issued blue prison jumpsuit, orange slides, and a white mask.
He was sitting in a wheelchair because he had been shot in the leg by police officers.
Police surrounded the store on Monday. After killing 10 people he took off his clothes and surrendered and then asked to speak to his mother.
Alissa was using a Rugers AR-556 which is a style of a shortened assault rifle. He bought it a week before the massacre on March 16.

Alissa had ranted on social media about Islamophobes hacking his phone and complained about President Donald Trump’s immigration policies.
His brother-in-law revealed that he worked in the family’s Middle Eastern restaurant, The Sultan Grill, and that he lived in their basement.
He told The Sun on Thursday that the killings had devastated their family and that his 65-year-old father Moustafa hadn’t stopped crying since he found out his son was responsible for them.
