CHARLESTON, SC (WCSC) - A James Island man convicted of killing his girlfriend has been sentenced to life without parole.
A judge sentenced 30-year-old Robert Kronsberg to life without parole Tuesday morning for the brutal murder of Tasha Lucia. He faced a sentencing of 30 years to life.
Kronsberg reportedly cursed at the judge as he read his sentencing. He was escorted from the court room while Lucia's mother sat crying with loved ones.
Last week, a jury found Kronsberg guilty for the murder of Lucia. Kronsberg was also found guilty of possession of a weapon during the commission of a violent crime.
Authorities say Kronsberg stabbed his 25-year-old girlfriend 15 times at an apartment they shared in February of last year.
At Tuesday's sentencing hearing, Judge Young said that while the murder struck him as a crime of passion, he can't look past the details of the crime.
"You thought she was dead and walked away from her," the judge said. "Heard she was alive and walked back to finish her off."
Kronsberg's lawyers claimed that their client killed Lucia in the heat of passion during an argument over her ex-boyfriend. During Tuesday's sentencing hearing, they asked the judge for a sentence Kronsberg "can live through," such as 35 years with five years probation.
Prosecutors asked for a life sentence.
Kronsberg's mother addressed the court Tuesday, saying her son is deeply remorseful, crying "what have I done?" while in jail.
"I'm so sorry I took her away from you. I loved her very much," Kronsberg said to Lucia's mother before he eventually broke down crying.
Lucia's mother chose to not speak at the sentencing hearing.
Co-workers and friends of Lucia testified last week they went to the apartment the couple shared when they couldn't reach Lucia by phone.
They testified that they gained entry into the apartment by going through a window and discovered Kronsberg snoring loudly in one bedroom and Lucia's body covered with a blanket that concealed a knife sticking out of her chest in another bedroom.
According to Polensky, he received a text message from Kronsberg, who he worked with at a James Island pizza restaurant.
"I had gotten a text that said 911 four times over in a row," Polensky said in court on Wednesday.
"So I called him and then he told me not to talk on the cell phone, that to just call him from the work phone."Polensky said when he called Kronsberg back, Kronsberg said,"Don't freak out, but I just killed my girlfriend."
