Police are looking for two women who have disappeared in separate cases in Dartmouth.

On Monday, police asked for help locating 45-year-old Donna Lee Sweeny and 24-year-old Patricia Angela Mahaney.

Sweeny was walking from Second Street to Lakecrest Drive in Dartmouth on Sunday around noon, but never arrived at her destination.

Police say she requires medication and it's unusual for her not to contact friends and family.

Mahaney was last seen leaving the Dartmouth General Hospital on Jan. 30.

She also has not been in contact with friends and family since then.
