Police on Thursday arrested a suspect in the fatal shooting of Racine, Wisc., Officer John Hetland on June 17.

The officer, a 24-year veteran of the department, was at a local tavern when a robber "went behind the bar and demanded money and wielded a gun," according to Kenosha County Sherrif David Beth.

Hetland jumped behind the bar to tackle the suspect but was fatally shot by the man, who then fled.
