Love triangle said to be behind pro cyclist's murder as manhunt for suspect continues

An international manhunt is underway for the suspected killer of professional cyclist Moriah Wilson. 

Authorities say Kaitlyn Armstrong, a 34-year-old yoga teacher, shot and killed Wilson, 25, in a fit of jealous rage, allegedly for having an affair with Armstrong's boyfriend, Colin Strickland, who is also a top-rated professional cyclist.

On the night she was killed, Wilson was in Austin, Texas preparing for a race.
