Colleen Ronnei stealthily followed her son, keeping her distance so he wouldn't spot her. Then she watched as he bought heroin in an Edina mall parking lot last summer.
Ronnei was desperate to save Luke; he was desperate to be "clean" again. But the pull of heroin was overwhelming at times, testing his will to remain clean.
"I needed to get this drug dealer off the street," Ronnei recalled. She wrote down the dealer's license plate and went to the police. There was little they could do at that point, they said.
Less than a year later, Luke Ronnei was dead at 20 years old. So were two other young Minnesota men who bought drugs from the same dealer.
Now, amid their devastating heartbreak, the three mothers have found one another and a tinge of solace: the heroin dealer, Beverly N. Burrell, is in jail, charged with three counts of murder.
"Burrell is a known heroin seller and this time the heroin was bad," said Hennepin County Attorney Mike Freeman, whose office will prosecute the cases.
"Some had fentanyl in it. Some had methamphetamine in it," Freeman said. The mixture was deadly and "she sold it to them knowing it was bad."
Synthetic fentanyl, which recently began showing up in Minnesota, is being added to boost the potency of heroin. Nearly 50 times stronger than heroin, it's also proving to be more deadly.
