Detectives with the Unified Police department had been looking for him for nearly three weeks following the triple murder in Midvale.
Sunday night Police came to a home in Millcreek looking for a parolee who had violated his probation. But once there, police spotted Fotu.
"He refused to comply with commands.from out officers," says Lt. Justin Hoyal. "He physically resisted where they had to tase him."
It happened right outside Rod Shirley's apartment.
"I never did see him there before," says Shirley. "But (a friend) now remembers seeing him early in the morning at around three in the morning, coming and going."
Fotu was wanted after three people were shot to death inside a Midvale home last month.
David Fresques allegedly went from room to room and shot two women and a man. As for Fotu, police say Fresques relied on him to getaway.
"Our investigators believe that Fotu provided a car to Fresques in an attempt to getaway," says Lt. Hoyal.
Police are still trying to figure out if Fotu was even in the home when the murders happened or simply supplied keys. For now, the keys are what's leading to obstruction of justice charges.
"Its a huge relief to get him off the streets where we can now finish this case and bring some closure," says Lt. Hoyal.
Fotu was named a person of interest in the February slaying of three people; Omar Jarman, Shontay Young and Danielle Lucero.
David Fresques was named a primary suspect in the case and was arrested two days after the February 12th shooting.
