DETROIT – Spring cleaning is underway, but a few quick home checks could save homeowners money this season. Simple fixes at windows, doors, the hot water tank and the furnace can improve comfort and energy efficiency without a major investment.

Windows are a top spot for drafts. Homeowners should seal gaps and crevices around frames with the right material for the gap size — foam, or adhesive V-seal strips are common choices. Proper weatherstripping can reduce cold-air infiltration and make homes more comfortable.

Doors often leak in corners and along thresholds. Installing corner blocks can block drafts that sneak in around frames and thresholds.

“Every little gap and crevice that all adds up,” Eric Douglas, project manager at SEEL.

Hot water tanks can lose efficiency because sediment settles near the burner, forcing the system to work harder and potentially shortening the tank’s life. Flushing the tank periodically removes buildup and can restore performance.

Regular furnace filter changes keep airflow steady and protect HVAC components. Douglas said filters should be replaced about every three months.

“You do all these little improvements, and it can make a big difference,” said Douglas.

A killer-for-hire is now a convicted liar-for-hire.

Confessed hit man Vincent Smothers, who is serving up to 100 years in prison for a string of contract murders, had more time added to his incarceration following recent convictions for lying to a court and possessing a contraband cellphone, according to Michigan Attorney General Dana Nessel’s office.

In 2018, Smothers provided an affidavit to the Macomb County Circuit Court in which he lied about two shooting victims to help bolster another inmate’s claim that he’d shot the men in self-defense, Nessel said in a press release. The contraband cellphone, discovered in Smothers’ cell in May, uncovered the scheme, in which Smothers was paid to lie, Nessel said.

Smothers, 45, was sentenced Thursday in Muskegon County Circuit Court to 14 months to 58 months in prison for possessing a contraband cell phone. Smothers, an inmate in Freeland’s Saginaw Correctional Facility, was sentenced in Macomb County Circuit Court last month to one to 40 years for providing a false affidavit to a court, an offense that carries up to life in prison.

Smothers will serve the sentences consecutively — after his 50-year to 100-year second-degree murder sentence is completed — the Attorney General’s Office said. The recent sentences push Smothers’ earliest release date up two years to April 18, 2061.

“Providing false evidence undermines the hard work of the many police, prosecutors, judges, and jurors who work tirelessly to hold dangerous people accountable and make our communities safer,” Nessel said in a statement. “This conviction and sentence make clear that those who attempt to obstruct justice will face consequences, and my office will continue to defend the integrity of our criminal justice system with the full weight of the law.”

In 2010, Smothers was sentenced to 50 to 100 years in prison after pleading guilty to eight counts of second-degree murder. Smothers said he was paid by Detroit drug dealers to kill their rivals, although he also was contracted to kill Rose Cobb, the wife of Detroit Police Sgt. David Cobb, whom he fatally shot on Dec. 26, 2007, while she sat in her minivan in a CVS drugstore parking lot on East Jefferson.

In 2008, after being charged in connection with his wife’s killing, David Cobb killed himself.

A prison cellphone discovery kicks off Nessel’s investigation

In May, officials at the Earnest C. Brooks Correctional Facility in Muskegon County found a contraband cell phone in Smothers’ cell. The discovery kicked off the Attorney General’s investigation, Nessel said.

When authorities inspected the phone, they found communications between Smothers and Shannon Anderson, an inmate in another prison serving up to 40 years following his 2010 second-degree murder conviction. The text messages laid out a scheme in which Smothers was to be paid to lie about the shooting victims to make the killings appear to have been in self-defense, according to Nessel.

Smothers signed the affidavit in 2018, providing false details about the shooting, according to the attorney general. In February 2020, Anderson’s lawyer filed a motion requesting a new hearing based on new evidence — Smothers’ affidavit, Nessel said.

Anderson also was charged with obstruction of justice in Clinton Township’s 41-B District Court. An April 2 preliminary examination is scheduled before Chief Judge Sebastian Lucido. Shannon’s attorney, Mariell Lehman, did not respond Friday to a phone call requesting comment.
