Christina Marie Schalk, 31, of Perry, faces three felony counts in connection with the October 2011, death of Karen Sue Caldwell, 47, also of Perry.
Caldwell died unexpectedly at her home on Friday evening, Oct. 28, 2011. She was formerly employed at Perry Machine and Die, and Country Kitchen in Hannibal.
In Ralls County Circuit Court on Tuesday, Rodney J. Rodenbaugh, prosecuting attorney, added a third count to two previously filed counts against Schalk.
Schalk is charged with:
I Delivery of a controlled substance, a Class B felony;
II Involuntary manslaughter in the first degree, a Class C felony; and
III Murder in the second degree, a Class A felony.
In Count III, Rodenbaugh charges that between the 25th day of October 2011, and the 28th day of October, 2011, the defendent delivered heroin, and in the perpetuation of the felony, Karen Caldwell was killed by heroin overdose.
Dressed in an orange jumpsuit belted at the waist, ankles and wrists in chains and with her hair pulled back in a French  side braid, Schalk stood before the judge and waived the formal reading of Count III on Tuesday. She is represented by Jeremy James Beaird of St. Louis.
A plea/trail setting for Schalk had been scheduled for Tuesday on separate charges, including burglary in the second degree, a Class C felony, and theft/stealing, a Class C felony.
Schalk was arrested last summer by the Ralls County Sheriff’s Department following a month-long investigation into the July 8th burglary of the Junction Convenience store in Perry.
She also faces four theft/stealing charges, and eight forgery charges, dating to the spring of 2013.
The prosecutor and defense attorney agreed to delay trials for the lesser charges until the more serious manslaughter/murder case is resolved.
“The outcome of 254 (the manslaughter/second degree murder case) may mean no trial for the others,” the defendant’s lawyer told Judge Rachel Bringer Shepherd.
The judge scheduled a two-day jury trial for May 20 and 21, at the Ralls County Courthouse in New London. A pretrial conference has been scheduled for 10 a.m. May 6.
The judge set 10 a.m. June 3, for a disposition/trial setting on the lesser charges.
Schalk is being held in the Marion County jail.
