Update 10/20:Gunman ambushed shooting victims after birthday celebrations

ORIGINAL STORY: Just before 2 a.m. Thursday, callers began dialing 911 to report a shooting west of Colorado State University’s campus.

Within minutes, police vehicles were swarming the area.

Three people are dead and another is injured after the incident at 720 City Park Ave. — marking the deadliest shooting in Larimer County in more than a decade.

A Colorado State University student is among the dead, and police confirmed the suspect is also deceased.

Details on what exactly transpired were limited Thursday evening, but police confirmed the suspect likely knew at least one of the victims.

The Larimer County coroner identified 22-year-old Savannah McNealy as one of the shooting victims. The coroner ruled her death a homicide by multiple gunshot wounds, according to a news release by the office.

The coroner intends to release the identification of the other two people who died, as well as the cause and manner of their deaths, on Friday.

McNealy was a student at CSU, the university confirmed. CSU’s online directory indicated that McNealy was studying liberal arts, art and art history. She was also listed online as a designer for CSU Life, a monthly campus publication.

The small neighborhood near Campus West is heavily populated by CSU students — filled with apartment complexes and fraternity and sorority houses.

As the sun rose Thursday, the police investigation continued. Red and yellow police tape encircled the complex. Police officers stood watch around the blocked area, and neighbors watched from their balconies.

Police cruisers lined the block, and an interagency command post was stationed on-scene. The RV-like vehicle functions as a mobile police station so officers have access to computers and can coordinate with other agencies during large-scale investigations.

Brooke Ehlers lives in a nearby apartment and said she was up late studying when she heard multiple gunshots and the sound of a woman screaming just before 2 a.m. She called 911 and said that within minutes, police vehicles were swarming the area.

CSU police first alerted the campus to the shooting about 2:35 a.m. The alert provided a description of a suspect and warned people nearby to stay inside. They posted two subsequent alerts in the early morning hours, and an “all clear” about 4:50 a.m. — shortly after Fort Collins police confirmed that they were no longer searching for suspects.

Jessica Sanow-Smith, a CSU graduate student, lives across the street from the scene. She said she was asleep at the time of the shooting but her husband, Luke Smith, heard multiple gunshots in the early morning hours and checked to make sure their doors were locked.

"I just woke up and had text messages from friends like, 'You live there. Are you OK?' And then I saw a bunch of emails on my phone (from CSU)."

Sanow-Smith said her husband thought the shots were fireworks at first because there are often fireworks in the area.

Lief Youngs, a resident of the apartment complex where the shooting took place, said he slept through the incident, but his roommate woke him up around 4 a.m. to tell him about it.

He said residents who had cars parked inside the crime scene tape were not able to move their vehicles. People who live inside the taped-off area had to leave their homes through back doors to avoid the crime scene or have a police officer escort them to and from their front doors, he said.

The Fort Collins police investigation is ongoing.

Emergency communications indicated the injured victim was rushed to Medical Center of the Rockies in Loveland, but police did not share details about the severity of the victim’s wounds.

CSU issued a campus email Thursday afternoon with information about the shooting and resources for the campus community.

"We are deeply saddened by this terrible loss to our campus community and will share more information as we have it," the statement said in part.
