car alarm going off early in the morning

See this message from a 1st Street NW resident:

I live on 1st St. NW between Randolph and S NW. For the past two or three weeks, someone`s car alarm (on 1st St., I think) has regularly been going off as early as 7 a.m. (including the weekends) and is allowed to continue for minute-long stretches of time. It`s immensely disruptive and annoying, as you can imagine.

I don`t want to be accusatory or shame a fellow neighbor; I just want the car alarm to stop.
