Six students who shut down the Highway 1-Highway 17 interchange in Santa Cruz with a human blockade were sentenced on Monday and offered their first public apology since the incident outraged the town back in March.A judge sentenced each University of California Santa Cruz student to each serve 30 days in jail. Attorneys, however, said the students may not actually spend any time behind bars. Instead, they could end up with just ankle monitoring bracelets and frequent check-ins with probation officers. A restitution hearing is happening on Tuesday, and the students could be ordered to pay up to $40,000 to local law enforcement. MUG SHOTS: 6 UC Santa Cruz Highway 1 studentsThe six students who protested university tuition hikes and police brutality by blocking Highway 1 for four hours were Ethan Pezzolo, 19, of Santa Cruz; Alexander Pearce, 19, of San Francisco; Sophia Dimatteo, 19, of Sherman Oaks; Janine Caceres, 21, of Los Angeles; Lori Nixon, 28, of Santa Cruz; and Sasha Petterson, 19, of Santa Cruz.On Monday, Pearce and Dimatteo said they had good intentions, but added that they are sorry for the "unintended consequences" of their civil disobedience. The group pleaded no contest in May, and prosecutors believe the students got off easy.A March 3 traffic nightmare began at 9:30 a.m. when a U-Haul van dropped off supplies needed to create an elaborate human blockade that law enforcement would not be able to quickly dislodge. Students linked their bodies together with chains, pipes, and trash cans filled with cement. Crews had to use jackhammers and sledge hammers to get the students off the highway.The group was arrested on charges of conspiracy, creating a public nuisance, refusing to comply with officers' orders, and resisting arrest. However, prosecutors only charged them with misdemeanor creating a public nuisance and misdemeanor resisting arrest. If the case had gone to trial and the students were found guilty, they could have faced 18 months in jail.Santa Cruz residents were outraged by the students' actions, and a viral petition was created online demanding that UCSC Chancellor George Blumenthal expel them.University administrators decided to suspend the students for 10 months and require them to complete 100 hours of community service. They will not be allowed back on campus until Jan. 1, 2016, and the university may hand down additional sanctions.
