Eldrick Broom, 27, was arrested Thursday on charges he sexually assaulted and then murdered Rosanna Camilo, a Dominican resident who had moved to Boston to obtain medical care for her young son.

Broom is scheduled for arraignment today in Dorchester District Court on charges he strangled Camilo in her 50 Fairlawn Ave. apartment on Nov. 21, the Suffolk County District Attorney's office reports. The DA's office says Broom gained access to her apartment building through an associate who had formerly lived there.

Camilo, daughter of a prominent Dominican broadcaster, left three children.
