Man Accused Of Killing Collingswood Sisters Detained Until Trial

COLLINGSWOOD, NJ — More than two months after a Burlington County man was arrested in connection with the murder of a pair of sisters in Collingswood, 44-year-old Mark Lyczak, of Medford, has been detained pending further court proceedings, according to the Camden County Prosecutor’s Office.

Lyczak’s pre-trial detention hearing was held Friday morning. He was arrested on Dec. 30 and charged with two counts of murder in the deaths of 48-year-old Colleen Brownell and her 41-year-old sister, Alysia McCloskey. He is also charged with attempted murder in the stabbing of a third woman in the same incident.

Under Criminal Justice Reform rules, the court may decide if the defendant is let out on bail or if he must be detained until trial. His next court date had not been set as of Friday morning.

Brownell and Lyczak were dating, but Brownell left him when he became overbearing and she became scared. Brownell obtained a restraining order against Lyczak and then moved in with her sister.

Brownell intended to move to Florida, to be closer to her son, who she had given up for adoption nearly 30 years ago, according to nj.com. They reconnected in 2016.

Lyczak is accused of fatally stabbing Brownell and McCloskey in their home on Saturday, Dec. 30. Both women were pronounced dead on the scene.

Police found Lyczak on top of the third woman with a knife in his hand. He was arrested, and she was hospitalized. He has been in the Camden County Correctional Facility since his arrest.
