A vigil was held Monday night for a Massachusetts woman who was killed over the weekend after going to a party in Lowell.
Police have still not made an arrest in the beating death of 44-year-old Gloribel Orengo, but her family says she knew the killers.
Family and friends who gathered at the candlelight vigil where she was killed are still in disbelief.
"It was horrible. I’m still in shock," said Orengo's friend, Deb Carroll. "I don’t know how to say bye to my friends. She was my best friend, she was like my sister."
Investigators say Orengo was at a party at the Westminster Village apartment complex on Pawtucket Boulevard when a fight broke out and spilled into the parking lot.
Orengo’s son, Luis Anthony Barreto, says his brother, who has Down Syndrome, was with their mother as a group attacked her.
"He started saying, 'no mommy it’s OK, get up,' Barreto recalled. "He kept saying it's his fault. I told him it's not his fault. He keeps saying he’s sorry - it just breaks my heart."
Family members said Orengo was a mother of four and grandmother of three.
Her fiance Miguel Morales, said in the 24 years they were together he can’t imagine who could brutally attack her.
"If you needed something she had it, and she was just the best," said a heartbroken Morales.
