Tributes poured in for Barquin, with Iowa State's head women's golf coach, Christie Martens telling local media the young golfer was a "beautiful person who was loved by all her teammates and friends".
The body of Barquin Arozamena was found dead by police by the 9th hole of Coldwater Golf Course in Ames, Iowa on Monday.
"She had been stabbed in the upper torso, head and neck", Huff said, adding that the attack had happened in "broad daylight", sometime between 9:30 and 10:30 a.m.
Colin Daniel Richards has been charged with first-degree murder.
Barquin Arozamena, a Spanish native, was a Big 12 champion and Iowa State's female athlete of the year.
As news of the tragedy was disseminated, many people and organizations began to send their tributes to the slain golfer.

The suspect, a woman who is reportedly 52 years old, was found in the basement with self-inflicted knife wounds to her wrists. CBS New York reports that the daycare was in a home and it was not yet clear if it was being run as a licensed care center.
Arozamena was going to be on the field at halftime of Saturday's game to be honored as Iowa State's female athlete of the year.
Barquin was remembered as one of Iowa State's most accomplished golfers and a bright engineering student. Instead, football players will wear helmet decals with her initials to mourn the loss. A second acquaintance told police that Richards arrived at his nearby home on Monday appearing "disheveled and covered in blood, sand and water" before bathing and leaving.
Athletic Director Jamie Pollard was overcome with emotion as he addressed the media Tuesday on losing a member of the Cyclone family. She won the 2018 Big 12 championship, an annual tournament contested between 10 leading USA sports universities, and was crowned European Ladies' Amateur champion in July. Ames police said she had been "assaulted".
A witness also said that Richards allegedly talked about "having an urge to rape and kill a woman", CBS reported.
Richards was sent to prison a year ago only after he tested positive for methamphetamine and marijuana, failed to complete an anger-management course he started four times and didn't pay court-ordered fees to a halfway house, court records show. In one case, the Iowa State Patrol seized a long knife from him during a traffic stop. In another, he threatened to return to a convenience store to shoot clerks after they caught him shoplifting.
