Two men have been arrested in connection with the murder of a UCLA student last week.
Andrea DelVesco’s body was found Sept. 21 after a fire was extinguished in her Westwood apartment.
Alberto Medina, 22, and Eric Marquez, 22, were arrested over the weekend.
Medina was arrested at his home in Fresno Saturday night and he is being held without bail. Marquez was arrested at his home in Westwood Sunday and he is being held in lieu of $1 million bail, according to LAPD.
Fresno State University confirmed Monday night that Medina is currently enrolled at the school as a junior with a double major in social work and pre-psychology. Marquez is a student at UCLA.
Police had asked for the public's help with any information that may help lead them to the person responsible for the death of the UCLA sorority member they believe was killed before her apartment was set ablaze.
DelVesco was a member of the Pi Beta Phi sorority.
LAPD Detective Lauren Rauch confirmed to NBC4 last week that there is evidence leading investigators to believe DelVesco was murdered prior to the blaze in her apartment, and that the fire was likely set in an attempt to cover up the killing.
The manner of her death has not been disclosed, and the relationship between DelVesco and the two men was not immediately available.
Investigators do believe her slaying was an isolated incident.
DelVesco was remembered as a "fearless giver" with a "contagious spirit," Pi Beta Phi chapter president Jacquie Medeiros said in a statement.
DelVesco, 21, was a fourth year student, double-majoring in Spanish and psychology, according to Facebook postings. Last year, she had been honored by her sorority as an "angel of the week."
Like many of her sorority sisters, DelVesco lived apart from the house on sorority row in an apartment on the west side of campus.
Almost immediately after the fire was extinguished, arson and homicide investigators were called in.
A woman's voice was heard yelling, "get out," and a man had been seen leaving the apartment after the fire started, a neighbor who identified herself as Reina said she was told by a friend of the victim.
DelVesco is from Austin, Texas. Her parents flew to Los Angeles and met with a coroner's investigator.
DelVesco was remembered as an enthusiastic employee at both the Jamba Juice in the UCLA Student Union, and at a Brentwood law firm, the Biren Law Group, where she had begun working during summer.
She had a "great spirit," said Dee Dee Biren, who recalled meeting DelVesco on a plane trip and being impressed with her attitude and outgoing nature.
