"Both of them would have been great spouses and parents, and it's shame they didn't get to do that," Concordia men's basketball coach Ken Ammann said.
Concordia University Irvine is a Lutheran institution and its athletic teams are known as the Eagles. Lawrence and Quan met when their collegiate careers overlapped.
"Keith was a junior here and Monica was finishing up and getting her master's," Ammann said.
Lawrence and Quan were "two of the greatest people that have been at Concordia and it's a terrible thing that people like that were murdered for no reason," Ammann said. Lawrence, 27, and Quan, 28, were slain Sunday night inside Lawrence's car in Irvine. Police suspect they were killed by Dorner, a fired Los Angeles Police Department officer believed to be motivated by revenge.
Lawrence, who played point guard, was a member of the men's basketball team from 2006 through 2008. In 2007, he sank a three-point shot that sent the team into a fourth overtime during a semifinal game of the National Association of Intercollegiate Athletics tournament.
The Eagles went on to win that game, played against Robert Morris University-Illinois. The victory matched them against Oklahoma City University, which won the title.
Lawrence majored in business administration, but pursued a career in law enforcement. He attended the Ventura County Sheriff's Academy after college and in August, obtained a job with USC as a public safety officer.
"He was really happy when he got the job last summer. He thought that it was a perfect start," Ammann said.
Quan played basketball for Concordia from 2005 through 2007. She earned a bachelor's degree in exercise sports science in 2007 and a master's in coaching and athletic administration in 2009.
"Our campus community is shocked and saddened by this tragic news," Concordia University president Kurt Krueger said in a statement. "Our prayers go out to the families and friends of Monica and Keith and know that we mourn along with them."
She worked as an assistant coach for Concordia from 2007 through 2009. She also coached for California Lutheran University in Thousand Oaks before becoming assistant coach for Cal State Fullerton's women's basketball team.
Quan also played high school basketball for Walnut High School, where she is a member of the Hall of Fame.
Quan's father Randal Quan is a retired Los Angeles Police Department captain who after becoming an attorney, represented Dorner during a 2008 departmental hearing.
The LAPD fired Dorner, who was accused of making false statements. Dorner claims in an online manifesto that he was wrongly fired for reporting another officer's unjustified use of force.
Randal Quan is among several people Dorner blames for his firing. Dorner's manifesto includes his declaration of a one-man war against law enforcement officers and their families. "I never had had the opportunity to have a family of my own. I'm terminating yours," Dorner wrote.
Dorner is also alleged to have killed one Riverside police officer and critically wounded another in an ambush attack early Thursday mornings. The officers' names have not been disclosed.
As of late Friday, several Southern California law enforcement agencies are involved in an extensive manhunt for Dorner in the Bear Valley area. A burning Nissan Titan pickup truck believed to be Dorner's was found in the Bear Mountain ski resort parking lot Thursday morning.
