The man convicted of killing his estranged wife and her 11-year-old son received two life sentences without the possibility of parole, plus 42 more years, in Montgomery County Monday.
Curtis Lopez was charged in October 2011 with the deaths of Jane McQuain, 51, and her son, William. On Monday, he was sentenced to one life sentence for each death, plus 30 years for child kidnapping and 12 years for robbery.
Family members and friends of the victims made statements in court Monday about the impact of their deaths.
I haven't used your name, you are nothing, not a person," Jane McQuain's cousin told Lopez in court. "I will forget your name as society will when they take you to jail."
Lopez -- an ex-convict who married Jane McQuain while he was in prison -- entered an Alford plea in January.
An Alford plea means that the defendant does not admit guilt but acknowledges that there's enough evidence for a conviction.
Prosecutors say Lopez killed his wife by hitting her with a dumbbell and stabbing her with a kitchen knife inside her Germantown apartment last fall. She had been dead for 10 to 12 days before her body was found after an acquaintance filed a missing persons report.
Authorities continued to look for William McQuain for about a week before his body was found Oct. 18 in a wooded area near a Liberty gas station in Clarksburg, Md.
By that point, Lopez was already in police custody. He had been arrested at a North Carolina motel and charged with one count of first-degree murder the day after Jane McQuain's body was found.
The boy had been beaten to death with a baseball bat, authorities said. They didn't believe William knew about his mother's death.

The judge made his thoughts clear as he addressed Lopez Monday.
"You stabbed Jane McQuain and crushed her skull with a dumbbell. You took William from a sleepover and crushed his skull. This was a person who called you dad," he said.
Surprisingly, Lopez took the opportunity to respond to the judge.
"Thank you for treating me with decency during this whole process," Lopez told the judge.
He then addressed the family of the victims, telling them he's sorry for their loss.
A surveillance camera at a nearby self-storage facility where Jane McQuain rented a unit captured video of William and Lopez together on Oct. 1, police said.
The video showed Lopez and the boy entering and leaving a unit at the facility. William appeared to be in a playful mood, showing no signs of distress, police said. Sources said the video showed McQuain rollerblading in the parking lot at the facility.
Prosecutors say the murders were motivated by Lopez's desire to steal Jane McQuain's car -- which he had promised to give to his girlfriend -- and other valuable items after McQuain inherited $80,000 from an uncle.
Lopez loaned the vehicle to his girlfriend in Charlotte, who was involved in an automobile accident that eventually led to his capture.
In an October 2011 statement, the McQuain family said that William was a spirited boy and outstanding athlete. Jane McQuain overcame adversity in her life, which the family said took on new meaning when William was born.
