Julia Niswender, 23, went to Eastern Michigan University. She lived in an off-campus apartment with roommates and was inside her room dead, left there for days as her bedroom door was locked.
Police discovered her body on December 11, where she was left in her bathtub. Police noted that her room was disheveled and a few items were missing.
They immediately ruled that her death was a homicide, but have not released many details as to what made them come to that conclusion. They said she died of asphyxiation by drowning.
Now, the Duvall Group Investigations PLLC, is offering a $10,000 reward for any information into the case.
"We are confident that the police department will find justice for Julia and my family," her mother Kim Turnquist said.
"We are just really hoping that this helps spread the word and helps catch whoever did this as soon as possible," her twin sister Jennifer said.
Ypsilanti Police Detective Sgt. Thomas Eberts said they were ruling Niswender's death suspicious, as they found evidence in her apartment that led to "unanswered questions."
Once they found her death to be a homicide, they sent out a warning to all students on campus. Though she did not live at the college, she lived very close to campus.
Niswender had a bright future ahead of her. She was described as a girl who dreamed of being a broadcaster, and was outgoing, loving, and a kind friend to others.
"No one will ever understand what I am going through right now, but I just want to say thank you to everyone who has been calling, texting, emailing and posting and for all your support during this horrible time," her twin sister wrote on Facebook.
"Also, thank you to everyone who stopped by to visit with my family and I. I wish I could respond to each and every one of you but words can't describe how I feel. Julia was my twin, other half, and best friend. No one will ever understand the bond we shared. I love her so much and just don't know how I can go on."
"My beautiful sister didn't deserve this. Justice will be served even if it is the last thing I do! The rest of my life I will be living for her."
