INITIAL ALERTSMS

CU Alert: Boulder Police are responding to an active shooter at the King Soopers at Table Mesa and Broadway in south Boulder. AVOID THE AREA.
Sent at 3:28 PM MDT on March 22, 2021 -- nearly 60 minutes after the first shots were fired at approximately 2:30 PM MDT
The delay was widely criticized -- Williams Village student housing sits less than a mile from the King Soopers and some CU students lived directly across the street
Used the all-caps 'AVOID THE AREA' formulation common to CU Alert active-incident messages but without an explicit shelter-in-place directive
Issued no instructions about lockdown or shelter at CU facilities -- the threat was off-campus and the gunman was contained at King Soopers by the time the alert went out

CU Alert 2: Police asking people near 17th & Grove to shelter in place while they respond to reports of an armed, dangerous individual.
Verbatim text confirmed: The Bold CU one-year retrospective and KDVR live updates both quote this as the exact CU Alert 2 text sent at 5:27 PM MDT on March 22, 2021.
17th & Grove is approximately 2.5 miles north of the King Soopers in central Boulder, not near campus -- the precautionary shelter reflected an unverified report of a possible second suspect.
Boulder Police lifted the 17th & Grove shelter at approximately 6:20-6:30 PM MDT after determining the report was a barricaded suspect unrelated to the King Soopers shooting.
Demonstrated the difficulty of relaying second-hand municipal shelter orders through a university alert system -- CU forwarded Boulder PD's order verbatim as its own CU Alert.

Verified verbatimThe Bold CU one-year retrospective quoting the exact CU Alert 3 text, confirmed by KDVR live-update coverage112 chars
CU Alert 3: Classes beginning at 5:30 p.m. and later are canceled due to an ongoing police situation off campus.
Verbatim text confirmed: The Bold CU one-year retrospective and KDVR live updates both quote this as the exact CU Alert 3 text sent at 5:38 PM MDT on March 22, 2021.
Sent 11 minutes after the 17th & Grove shelter alert -- notably did not cancel classes already in session at 5:38 PM, only those scheduled to begin at 5:30 PM or later.
Used 'ongoing police situation off campus' rather than 'active shooter' or 'mass shooting' -- a softening that was criticized in The Bold CU's subsequent reporting.
Campus operations resumed the next day, Tuesday, March 23, 2021.
ALL CLEARSMS+3h 50m
Verified verbatimThe Bold CU one-year retrospective quoting the exact CU Alert 4 text, confirmed by KDVR live-update coverage104 chars
CU Alert 4: Per Boulder Police, no further ongoing threat. Witnesses should contact BPD at 303-441-3333.
Verbatim text confirmed: The Bold CU one-year retrospective and KDVR live updates both quote this as the exact CU Alert 4 all-clear text sent at 7:18 PM MDT on March 22, 2021.
The brevity of the all-clear -- 'Per Boulder Police, no further ongoing threat' -- reflects a deliberate pass-through of BPD's language rather than CU's own assessment.
The Boulder Police tip line number (303-441-3333) embedded in the all-clear is unusually operational for a campus alert -- directing witnesses to contact police while simultaneously informing the campus the threat was over.
At 7:18 PM MDT, nearly five hours elapsed between the first shots (2:30 PM MDT) and the formal CU all-clear, consistent with the length of the standoff before Al-Issa surrendered.
Context

Background

Shortly after 2:30 PM MDT on March 22, 2021, Ahmad Al Aliwi Al-Issa opened fire at the King Soopers grocery store at Table Mesa Drive and Broadway in south Boulder, killing 10 people including Boulder Police Officer Eric Talley. The store sits approximately 2 miles south of the University of Colorado Boulder's main campus and less than a mile from the Williams Village student housing complex. CU Boulder's first CU Alert did not go out until 3:28 PM MDT -- nearly an hour after the first shots were fired. By that point news of the shooting was widely circulating on social media, and many students reported panicking before any university communication arrived. Two follow-up CU Alerts went out at 5:27 PM (relaying a Boulder Police shelter order for 17th & Grove) and 5:38 PM (canceling classes scheduled to begin at 5:30 PM or later). Suspect Al-Issa was later sentenced to life without parole after a 2024 jury trial. The roughly 60-minute delay between the first shots and the first CU Alert was widely criticized by students and was a focus of internal review at CU.

Key Findings

First CU Alert went out at 3:28 PM MDT -- approximately 58 minutes after the first shots were fired at the King Soopers at 2:30 PM
Williams Village student housing sits less than 1 mile from the King Soopers -- some CU students lived directly across the street from the shooting site
Only three CU Alerts were sent the entire day; classes already in session at 5:38 PM were not canceled
The 60-minute delay was widely criticized and became a focus of CU's subsequent internal review
Demonstrates the gap between municipal active-shooter response and university notification systems for off-campus incidents -- a recurring challenge for urban-adjacent campuses
Outcome
Suspect Ahmad Al Aliwi Al-Issa was arrested at the scene and [convicted in September 2024 of 10 counts of murder](https://www.cnn.com/2024/09/23/us/king-soopers-boulder-shooting-trial-verdict) and sentenced to life without parole. CU Boulder canceled classes scheduled to begin at 5:30 PM or later. Boulder Police lifted the shelter-in-place advisory for the broader Table Mesa area at approximately 6:30 PM MDT. The delay between the shooting and the first CU Alert was widely criticized by students and was a focus of CU's subsequent internal review.
