LOWELL -- The Middlesex County District Attorney's Office reports there will be no further updates on the investigation into a Lowell woman's suspicious death until toxicology reports return from the state medical examiner's office.

MaryBeth Long, a spokeswoman for the office, said these reports can take weeks.

On Easter Sunday, police were called to the home of Elaine Sweeney, 52, at 189 Sparks St. According to Police Superintendent William Taylor, police responded at 2 a.m. to a medical-assistance call and found Sweeney dead inside the home. The residence is listed under Sweeney's name, McDermott, from a previous marriage, and she was married to Andrew "Andy" Sweeney.

Members of Sweeney's family have declined to comment. Many remember Sweeney, a native of the area who attended the Ste. Jeanne d'Arc school with friend Mayor Rodney Elliott, as a kind, loving person who was devoted to her family. She had four daughters, many of whom still live in the area, according to friends.

Officials from the District Attorney's Office and Lowell Police Department, along with the Massachusetts State Police, are reporting little information at this time as their investigation continues. There have been no arrests in the case and Long said Tuesday those in the neighborhood in Pawtucketville should contact the police department if they have concerns for their safety.

There was a strong police presence around Sweeney's home on Sparks Street throughout much of Sunday morning. A neighbor, Paul Smith, said he saw investigators searching through the backyard of the home and knocking on nearby residences' doors to ask questions.
