A 22-year-old man pleaded guilty Friday in Jackson County to the 2013 murder of a University of Missouri-Kansas City student singer.
Alonzo D. Ruff of Kansas City agreed during the plea hearing that he killed Aaron Markarian during a home invasion on March 21, 2013. He also admitted that he shot three other people and stole money and cellphones during the attack at a home just south of the Country Club Plaza.
According to a plea bargain announced at the hearing, Ruff faces a minimum of 20 years in prison and a maximum of 30 years at sentencing, which Circuit Judge Robert Schieber set for Jan. 9.
Markarian, 23, was a senior baritone at the UMKC Conservatory of Music and Dance. He had been set to graduate the following May with a bachelor’s of music in vocal performance.

According to court records and police, Ruff and Anthony J. Williams stormed a birthday party attended by eight college students and young adults, demanding drugs. One victim recognized Ruff from high school. Ruff opened fire as he and Williams prepared to leave.
In addition to one count of second-degree murder, Ruff pleaded guilty to three counts of assault, one count of robbery and five counts of armed criminal action.
A plea hearing for Williams is scheduled for Monday.
