December 2nd Update: According to a police affidavit on the fatal shooting that occurred on Alberta Drive in Gillette on November 28th, animosity between the victim and suspect may have been the result of a debt owed, and the attempt to collect that debt.
Mathew Boyer, of Gillette, aged 25, was shot twice in his torso after he answered the door at his home about 3:55 in the morning on the 28th. Boyer died as a result of that shooting. 9mm shell cases were found at the scene.
A witness told investigators that Boyer had arrived home at about 3:00 in the morning, after going to the bar with a friend. The witness also told investigators that she believed Boyer and the friend attempted to collect a debt owed to the friend from someone named “Todd,” who allegedly owed the friend back rent money.
Investigators later identified “Todd,” as Todd Sindelar, the man since arrested and charged in the murder. Sindelar allegedly became upset after hearing that Boyer and his associate had been to Sindelar’s residence looking to collect the debt. Witnesses also allegedly informed Sindelar that his residence had been damaged. Sindelar then allegedly told a witness not to call the cops, as he would be taking care of the issue himself.
An out-of-state witness also told investigators that Sindelar had contacted her a few minutes after the estimated time of the shooting. The witness told investigators that Sindelar told her something bad had happened; and told her some guys had been at his place and caused damage, and trashed it. He said he then confronted one of the guys and things got heated. The witness said Sindelar stated, “I shot him.”
Sindelar, age 21 of Gillette, was eventually arrested in South Dakota after his vehicle was located east on I-90, west of Rapid City. Sindelar failed to yield to Troopers for over 2 hours. His vehicle was eventually stopped when he ran over spike strips near Chamberlain, South Dakota. He was taken into custody for eluding, at that time. During the investigation Gillette Police found 9mm ammunition at his residence. He has since been charged with first degree murder.
