Today, before the Honorable Thomas J. Shusted, J.S.C., Mark Lyczak, 45, of Burlington County, pled guilty to two counts of First Degree Murder for stabbing Colleen Brownell and Alysia McCloskey to death and one count of second degree Aggravated Assault for stabbing his at the time girlfriend.
According to authorities, on Dec. 30, 2017, Mark Lyczak entered Alysia McCloskey’s home on East Narbeth Terrace in Collingswood looking for his ex-girlfriend, Colleen Brownell. During an altercation inside of the house, Lyczak stabbed all three victims.
Collingswood Police responded to the home after receiving multiple 9-1-1 calls for reports of a man armed with a knife. When police arrived, they found Alysia McCloskey laying on the front porch suffering from multiple stab wounds. Authorities then entered the house and located Colleen Brownell on the living room floor, also suffering from multiple stab wounds. Both victims were pronounced deceased at the scene.
Police found Mark Lyczak on the couch on top of his 43-year-old at the time girlfriend, who was also suffering from multiple stab wounds. The surviving victim was rushed to a nearby hospital where she was treated and eventually released.
The identity of the third victim is not being released at this time.
Police arrested Mark Lyczak at the residence. He was taken to the Collingswood Police Department where he was later charged.
Under the terms of the plea agreement reached by Assistant Prosecutor Lauren Pratter, Mark Lyczak will be sentenced to 47 years in New Jersey State prison for each count of murder and 10 years in New Jersey State prison for the aggravated assault. His sentences on all three counts will run concurrent. He will be required to serve at least 40 years of his sentence before he is eligible for parole.
The family of Colleen Brownell and Alysia McCloskey, who are sisters, was present in court for the plea.
Officials say Mark Lyczak will be sentenced on January 11, 2019 at 11:00 a.m. before the Honorable Thomas J. Shusted, J.S.C.
