Christopher Semmelmann, 32, was found deceased along the 3800 block of North Highway 87 in Big Spring, Texas, on December 15, 2023. Investigators say Semmelmann had been murdered at a residence in the 100 block of Jonesboro Road before his body was located on the highway.

An arrest warrant for 25-year-old Ray Alvarado was obtained on December 19, 2023, in connection with Semmelmann’s murder. That same evening authorities tied Alvarado to a string of violent incidents in Big Spring: a shooting at a convenience store on South Gregg Street that left 34-year-old Rosendo Deanda seriously wounded, a reported theft of a gray Chevrolet pickup from the 200 block of West 2nd Street, and a later shooting on Settles Street in which 55-year-old David Holsenbeck was fatally wounded. Officers apprehended Alvarado after a brief pursuit and foot chase; he was booked on murder charges and other outstanding warrants.

A separate indictment later named 43-year-old Michael Bullinger for murder and tampering with evidence related to Semmelmann’s death, showing the investigation involved multiple defendants. What information do readers have about Semmelmann, his movements before December 15, or additional witnesses who might help clarify what happened?
