PHILADELPHIA (CBS) — A Pennsylvania man is accused of murdering a woman after she rejected his marriage proposal.

According to CBS3, 34-year-old Christopher Ryan Tucker, of Albany Township, allegedly confessed to killing 19-year-old Tara Serino, of Lehigh County.

Authorities said that Tucker was caught attempting to steal a motorized combine from a farm in Illinois after his car broke down.

When he was arrested, he told police that authorities would find Serino’s body wrapped in a rug in his Albany Township home, and he admitted he killed her.

According to CBS3, Pennsylvania State Police were then sent to Tucker’s home, where they found Serino’s body. She had been strangled, her neck was snapped, her eyes were popped out and she had been beaten with a hatchet.

“He must have asked her to marry him, and when she said no, he just snapped,” Trooper David Beohm, with the Pennsylvania State Police, told CBS3.

A friend who knew both Tucker and Serino told CBS3 that the couple had only been dating for 5 months and Tucker had recently been in and out of treatment for mental illness.

CBS3 reports it will likely take at least a week before Tucker is extradited back to Pennsylvania and formally charged.
