A Derby man who strangled his girlfriend to death and stabbed her teenage son was sentenced Wednesday to life in prison, plus nearly 14 years.
Charles A. Beck, 40, will not begin serving the 165-month sentence for attempted first-degree murder until he is paroled on the first-degree murder charge, Dan Dillon, spokesman for the Sedgwick County District Attorneys Office, said Wednesday by e-mail.
Beck will not be eligible for parole until he has served at least 25 years of his life sentence, Dillon said. Sedgwick County District Court Judge Joseph Bribiesca handed down the decision.
Beck pleaded guilty last month to first-degree murder for killing 43-year-old Lonnie Staggs at a house in Derby near K-15 and 71st Street South where the couple lived with Staggs two children. According to court filings, Beck strangled Staggs on the morning of Sept. 1 and then attacked her 15-year-old son, Nathan Dorl, with a knife and attempted to strangle him with a cord.
Beck cut the teens neck and face, records show, before the boy escaped to a bedroom, where he locked himself in with his 11-year-old sister. Beck then fled the scene.
In the days after the attack, a friend of Staggs family told The Eagle that Dorl fought off Beck that morning and kept his sister safe.
He was so brave and strong, Angel Hallock said.
Police who responded to the house that morning found Staggs . Her son, who was also hospitalized, was treated for stab wounds to his throat and released.
Beck called 911 about 10 hours later and turned himself in to authorities in Texas County, Mo. He was arrested at a family members home in Moby, Mo., that night, according to information released by authorities at the time.
In addition to the count of first-degree murder, Beck admitted to one count of attempted first-degree murder in the April plea.
He had served time in prison for previous convictions, including violating a protective order and drug possession, dating back to 2006.
The homicide was Derbys first since 2004.
