It's a parent’s worst nightmare to learn that their child has been killed. It's even more heart wrenching when they have to find out via social media. That's what happened to Nikkita Milledge, whose son, Anthony Warren, was shot on Saturday. The 15-year-old, who was spending time with a friend on Friday, was shot outside an apartment in Indianapolis.

On Saturday, around 1:50 p.m. -- 50 minutes after he was shot -- Milledge called her son to find out where he was because he should already have been home. When she wasn't able to reach him, she looked on his Facebook wall for any information regarding his whereabouts.

“Saturday afternoon, I hadn’t heard from him and I called him at about 1:48 and he didn’t’ answer his phone. I later found out that at 1:48 Anthony was already dead. He had died at 1 o’clock,” Milledge said.

On Facebook, she saw consoling messages from friends of the victim who wrote on his Facebook wall. Milledge saw the messages before she was contacted by the police. 

“Someone put on Facebook, ‘RIP Anthony, I will miss you’ and then the phone calls started coming in to my house and cell phone,” she told Fox 59. “Very unbelievable that my son was gunned down in broad daylight." 

Police arrested and charged 19-year-old Brice Price on Monday with murder and conspiracy to commit robbery in the incident, the Indianapolis Business Journal reports. Investigators believe that he and Warren were involved in a planned robbery attempt of an unknown person when Warren was fatally shot.
