Through April of this year, 17 people in Hennepin County have died because of heroin.

Last year, there were 56 heroin-related deaths. That’s a record for the county.

People with active warrants are urged to turn themselves in so they don’t have to go through the embarassment of being arrested at their job or at home.

Authorities have a list of more than 160 people they will try to arrest this month.

Many of those people are repeat offenders with several active warrants.
