Bodies found stuffed in black bags in shed behind home

CLINTON TOWNSHIP, Mich. – A man found guilty of murdering his 18-year-old sister and her boyfriend in 2018 and leaving their bodies in a shed was sentenced to mandatory life in prison without parole on Tuesday.

Robert Marzejka, 24, was found guilty in November on two counts of first-degree murder. His sentencing was Tuesday morning before Judge James Biernat Jr. in Macomb County Circuit Court. He received the mandatory life in prison sentence and did not offer a statement in court.

Danielle Marzejka, 18, and her 19-year-old boyfriend, Seren Bryan, were found dead Aug. 27, 2018 in black bags in a shed behind the Rudgate Clinton Mobile Home Park near Groesbeck Highway and Metro Parkway, police said. They lived with Danielle Marzejka’s father and two brothers.

One of the brothers found the bodies when he noticed flies coming from the shed, according to police. He opened the shed and found two black plastic bags, police said. When he opened one of the bags, he saw a body part, according to officials.

Clinton Township police said Robert Marzejka’s 1999 Ford van was recovered in Toledo. He was arrested in Cincinnati, Ohio, on Aug. 29 on a murder warrant issued by the Macomb County Prosecutor’s Office.

Marzejka’s defense attorney has repeatedly claimed the defendant’s actions were due to mental illness, that Marzejka has had a history of mental illness and has been hearing voices.

Victim’s mother speaks at sentencing

Seren Bryan’s mother, Diane Bryan, did speak in court before the sentencing on Tuesday. She said her son’s official cause of death was suffocation after he was knocked unconscious. She said Seren suffocated after duct tape was placed over his face, he was bound and plastic bags were placed over his head.

She described her son as a loving and caring person.

“Each day I struggle to not let his final day affect me more than that day I first saw his heartbeat. I say to myself, sometimes out loud, you cannot keep Seren in that day. You can’t keep him in pain. Seren isn’t there anymore,” said Diane Bryan.

Prosecutors said Marzejka has shown no remorse for the murders. He stood silent as his sentencing was handed down. When asked if he wished to say anything, he simply shook his head and said, “No."

“You’re going where you belong,” said the judge.
