BOULDER, Colo. — The man accused of injuring and burning a group of people in Boulder with Molotov cocktails on Sunday had been planning the attack for a year, according to an arrest affidavit.
The suspect, Mohamed Sabry Soliman, 45, of Colorado Springs, is accused of throwing Molotov cocktails into a crowd of demonstrating people, injuring 12 of them, and yelling "Free Palestine," according to a federal arrest affidavit Denver7 obtained on Monday morning, and Boulder County District Attorney Michael Dougherty. A state arrest affidavit added that witnesses saw him using a commercial weed sprayer as a makeshift blowtorch.
Nobody was killed in the attack.
He is being held on multiple state felony charges, including 16 counts of attempted first-degree murder, six counts of first-degree assault against an at-risk victim, two counts of first-degree assault, two counts of possession of an incendiary device and 16 counts of attempted possession of an incendiary device. In addition to the state charges, he also faces a federal hate crime, according to the U.S. Department of Justice.
These charges may change, authorities said.
Initially, authorities said eight people had been injured and hospitalized. This increased after four additional victims were identified, District Attorney Dougherty said Monday. Of the original eight who were hospitalized, five have been discharged from the hospital and the other three remain at UCHealth University of Colorado, the hospital confirmed to Denver7.
The U.S. Department of Homeland Security confirmed Soliman is in the United States illegally. He came to the United States in August 2022 on a tourist visa that expired the following February.
On Sunday afternoon, the local group from the organization Run For Their Lives held its weekly walk to bring attention to the Israeli hostages held in Gaza. The Boulder group walks every Sunday and planned to do so at 1 p.m. at the corner of 8th Street and Pearl Street. Sunday was the start of the Jewish holiday Shavuot.
According to a state affidavit for Soliman's arrest, he arrived shortly before 1 p.m. and was dressed like a gardener so he could get as close to the group as possible. He had purchased flowers from Home Depot and the backpack sprayer, which he had filled with gas, the document reads.
Officers with the Boulder Police Department responded to the area around 1:30 p.m. after receiving reports of a man with a "blow torch" who was setting people on fire and throwing Molotov cocktails, the affidavit says.

What is ‘Run for Their Lives,’ the group that was attacked in Boulder?
Around 2 p.m., Soliman threw two lit Molotov cocktails at people who were participating in the gathering, the federal affidavit reads. The Molotov cocktails ignited and burned eight people.
When officers arrived, witnesses pointed to a shirtless man who was standing in the grass and yelling at the crowd, the state affidavit reads.
The Associated Press reported that after the initial attack, the suspect hid behind some bushes before reemerging and attempting to throw another Molotov cocktail, but appeared to accidentally catch himself on fire. The AP said he had been wearing what appeared to be a bulletproof vest.
He was then detained and brought to a hospital for medical help.

A Holocaust survivor is among the victims of Boulder antisemitic attack
The victims — four men, four women — were identified as between the ages of 52 and 88, and included one person who is a Holocaust survivor.
At the scene, law enforcement found a plastic container that contained at least 14 unlit Molotov cocktails, the affidavit reads. District Attorney Dougherty said later in the day that two additional ones were found, bringing the total to 16. Nearby, authorities found a backpack weed sprayer, which investigators believe may have contained flammable substance, the federal affidavit continues.
"The clear liquid in the glass bottles and weed sprayer were determined to be 87 octane gasoline, which was determined to contain xylene based on a field test," the document reads.

Law enforcement also found Soliman's vehicle parked nearby at Spruce Street and 13th Street.
Local and federal authorities interviewed Soliman on Sunday.
In that interview, he said he had researched how to make Molotov cocktails after he was denied the purchase of a gun since he is not a legal U.S. citizen, the state affidavit reads. He said he purchased most of the required materials in Castle Rock, constructed them and drove to Boulder, arriving at 12:55 p.m. He told authorities he threw two of the Molotov cocktails at the gathering, the two affidavits say.
"He stated that he wanted to kill all Zionist people and wished they were all dead," the federal affidavit reads, and he added that he would do it again.
He further explained that he "hated" the group and wanted to stop them from taking over "our land," which he said was Palestine, according to the federal affidavit.
Soliman told authorities he had been planning the attack for one year and was waiting until after his daughter had graduated from high school, which happened on Thursday.
They learned Soliman was born in Egypt, lived in Kuwait for 17 years and moved to Colorado Springs about three years ago with his wife and five kids, according to a state affidavit.
The AP reported that he worked as an Uber driver and was employed by a "Denver-area health care company working in accounting and inventory control, with prior employers listed as companies in Egypt." He said he had left an iPhone hidden in a desk drawer at his house with messages to his family, the federal affidavit said, and also left a journal at home.
The state affidavit said he has no criminal history listed in the National Crime Information Center.
Soliman is being held on a $10 million bond at the Boulder County Jail. He is expected in court at 1:30 p.m.
The Boulder District Attorney’s Office, Boulder Police Department, Federal Bureau of Investigations and Acting U.S. Attorney J. Bishop Grewell will hold a press conference Monday at 2:30 p.m. to announce the formal state and federal charges against Soliman.
The Anti-Defamation League has data showing 279 antisemitic incidents in Colorado last year. This marks a 41% spike year over year, they reported. Nationwide, the average increase over that same time period was about 5%.
