Two men have been charged with killing a pregnant mother on Christmas Day in what police have described as a contract killing.

Mashaun Jay Baker, 33, is accused of hiring Dion Jamel Green, 33, to shoot 31-year-old Jenna Schafer dead in an apartment in Junction City, Kansas, on December 25.

It remains unclear why he would have wanted the pregnant mother-of-two dead or how they knew one another.

It is also not known how far into the pregnancy Schafer was when she was killed.

In a criminal complaint filed on Tuesday, Geary County Attorney Krista Blaisdell gave few details about the death but suggested Baker hired Green to carry it out.

Green was arrested on December 25 hours after police found Schafer's body at 9.30am.

Baker was arrested on January 2.

Both men appeared in court on Monday on first degree murder charges.

Baker faces one for Schafer but Green has been charged with two; one for her and one for her unborn baby.

Further details of how much he was paid, if anything, to carry it out remain unknown and police are being tight lipped about the case.

It remains unclear why the men wanted Schafer, who had two daughters, dead

Geary County Attorney's Office did not immediately return DailyMail.com's inquiries for comment on Tuesday afternoon.

In an obituary, Schafer was described as a loving mother-of-two daughters.

Friends told how she had spent her childhood moving around with her parents because her father was in the military.

She was a stay-at-home mother who enjoyed 'social media, cruising and dolphins', it said.

Since she was found dead, her loved ones have been appealing for information about who killed her on social media.

None have yet spoken out about the suspects' arrests.
