What did police say happened to Carol Clark?

Rivera told authorities he purchased takeout for he and his mother sometime between 6 p.m. and 7 p.m. Saturday night, according to his criminal complaint. He told police he put fentanyl in his mother's iced tea, court documents state.

Fentanyl is a synthetic opioid that is more potent than heroin.

Sometime between 3 a.m. and 4 a.m. Sunday, Rivera placed his mother in her wheelchair and put her into her Toyota RAV4, according to officials. Clark had limited mobility and used a wheelchair or needed help walking.

She was conscious but in a "lethargic state" because of the fentanyl, when Rivera took her, officials said.

Rivera took his mother from their home in the 500 block of Berwyn Road to a shed on a property in the 4300 block of Waln Street in Philadelphia, charging documents state. He then shot her with a handgun multiple times, police allege.

Rivera took bolt cutters and removed the lock from the shed, put his mother in the shed, then replaced the lock, according to court documents. Investigators found her body in the shed early Monday morning.

How did the police begin investigating Carol Clark’s disappearance?

Police began investigating Clark’s disappearance Sunday afternoon, when Rivera’s brother, who lives in New York, was having a dispute over her whereabouts with Rivera.

Rivera’s criminal complaint states he texted his brother “911” about 7:30 a.m. Sunday. He called Rivera, who told him Clark had died, and that he has to come to Pennsylvania, court documents state.

When he arrived about 9 a.m., Rivera told his brother that she got sick and died, police said. He told her she was at a hospital in the Frankford section of Philadelphia.

Rivera's brother checked with nearby hospitals and could not find their mother. When he returned to the home, Rivera again told him she was at a hospital in Frankford, prompting his brother to check again.

When he returned to the home again, Rivera was not there, the brother called 911.

Sunday was Clark's birthday, and Rivera’s brother had sent her a text message the night before, but had not heard anything. Additionally, Clark had plans for Sunday. It was unlike her to not respond to a text message.
