Tony Keller and Karmen Anderson spent hours researching together at the University of Vermont.
When Anderson graduated in May, she followed her former engineering professor to Tampa. They researched together and lived in the same apartment complex.
Now, Temple Terrace police want to know why Anderson's boyfriend, Corey Crandall, 22, opened fire on Keller and Anderson on Wednesday night, killing them, before turning the gun on himself in an apparent murder-suicide. The shooting happened about 10:10 p.m. at Preserve at Temple Terrace, a gated apartment complex on Fletcher Avenue where all three lived. Off-duty Temple Terrace Officer Todd Lyons heard shots from Apartment 926, the second-floor apartment Anderson and Crandall shared at 13155 Mallard Landing. Lyons ran to the apartment and saw Crandall outside, gun in hand. Lyons shouted for Crandall to stop, but he ducked into the apartment, fatally shooting himself, police say.
In the apartment, police found an injured Anderson and Keller's body. Both suffered gunshot wounds. Anderson was taken to University Community Hospital, where she died. Police have no motive, police spokesman Michael Dunn said. What happened between the trio seems a mystery.
Keller won a Fulbright Scholarship in 2004, which led him to Cairo University in Egypt in spring 2005. He had bachelor's degrees in engineering and science from Oregon State University, a master's in bioengineering from the University of Washington and a doctoral degree in mechanical engineering from Vanderbilt University, says an OSU Web site. He spent 15 years at the University of Vermont.
Crandall's family could not be reached. Anderson's father, Karl, declined comment. Keller's son, Jeff Keller, lives with his mother, Sally Keller, in Vermont. He said his parents had divorced. Sally Keller declined to comment.
Dr. Roy Sanders wooed Keller to Florida a couple of years ago, said Sanders' wife, Melanie Sanders. Sanders and Keller met years before at Vanderbilt.
Keller, who was engaged, was set to close on a house in Tampa on Thursday, said his real estate agent, Mary Esther Parker. When he didn't show, she called him.
