BALTIMORE (AP) — Police say on Monday they will clear the scene where a Baltimore police detective was shot and killed.

The crime scene in West Baltimore’s Harlem Park neighborhood has been locked down since Wednesday, when 43-year-old Detective Steve Suiter was shot in the head while working a case. He died a day later.

On Sunday, the American Civil Liberties Union of Maryland issued a statement questioning the length and intensity of the police presence in the neighborhood.

Police said Sunday that they’ve needed to keep the crime scene off limits to recover evidence and conduct a thorough investigation.

Also on Sunday, a GoFundMe page set up to benefit Suiter’s family attracted more than $5,000 in donations within four hours of its establishment.
