The mother of a University of Colorado Boulder student who was found dead in Boulder Canyon last month, wrote Tuesday night that her daughter was found with only one shoe and her purse was found ripped, leading her to believe “there was a struggle.”

Megan Trussell, 18, was found dead on Feb. 15 in “hard-to-reach” terrain near the 40-mile marker of Boulder Canyon Drive, just west of the Canyon Park and Boulder Canyon Drive intersection.

The Boulder County Sheriff’s Office said based on the current information, foul play is not suspected.

“As with any major ongoing investigation, certain details cannot and should not be released to protect the integrity of the case,” Detective Commander Jeff Pelletier said in a news release from the sheriff’s office.

“We understand the community’s interest and the desire for information, but we must maintain a careful balance. Based on the circumstances known at this time, foul play is not suspected. However, the case remains open and under investigation.”

On Tuesday, her mother, Vanessa Diaz, took to Facebook to say her daughter was found wearing only one 3-inch platform tennis shoe.

Diaz wrote that she and trusted friends searched the area that Trussell was found in this weekend and the other shoe was not there.The Boulder County Sheriff’s Office confirmed Tuesday that Trussell’s purse was found. An anonymous source confirmed with the Daily Camera on Tuesday that the purse was found at about 11 a.m. Wednesday, March 5, near U.S. 36, just southeast of Table Mesa Drive by the Dry Creek Ditch Number 2, more than 6 miles from where her body was found.

Diaz wrote on Tuesday night that the side seam on the purse was found ripped out and, having sewn the purse herself, she said she knew the seam was reinforced “very thoroughly.”

“Megan called her purse her ‘security blanket,’ and she would not have ditched it along with the prized possessions that she carried inside it. Someone ripped this purse from her,” Diaz wrote.

“The damaged purse and the missing shoe lead me to believe there was a struggle, or, at the very least, another person with her when she died,” Diaz added.

Diaz also wrote on Facebook that Trussell’s phone has not been found.

“Although the cause and manner of death has yet to be determined by the Boulder County Coroner’s Office, we still have no reason to believe that there is, or was, a threat to the community,” the sheriff’s office wrote in a news release.

The final autopsy report of Trussell has not yet been completed, according to the Boulder County Coroner’s Office.

Trussell was seen leaving her campus dorm, Hallett Hall, at 9 p.m. Sunday, Feb. 9, six days prior to her body being found in Boulder Canyon.

She was wearing a blue or gray jacket, dark-colored yoga-style pants and white platform sneakers, according to Christine Mahoney, a spokeswoman for the CU Boulder Police.
