Nicholas ‘Nick’ Wu, 26, was last seen around 5 p.m. Sunday leaving his home in the 24900 block of West Clinton Avenue in unincorporated Round Lake.

Wu left on a longboard skateboard after an argument with family members, according to the Lake County Sheriff’s Office. Family members are concerned due to Wu’s agitated and at times violent state.
