A suspect has been arrested in the beating and strangulation death of his 60-year-old roommate Tuesday night at their apartment in southeast Houston.

John A. Kamenicky, 38, is charged with murder in the slaying of Mark Ellis, which happened at about 6:30 p.m. at 7800 Detroit, according to the Houston Police Department.

Police said Ellis' brother told investigators he had not heard from his sibling for several days and became suspicious when he went to the apartment and saw the front door open. When he went inside, he found his brother's body wrapped in a blanket that was tied with an extension cord.

Police said an autopsy revealed Ellis had been beaten and strangled. There were no signs of a struggle inside the apartment.

Later, investigators determined Kamenicky was the suspect in the case. He was arrested Wednesday without incident.

Investigators did not reveal what led them to Kamenicky. They also did not release a possible motive in the case.
