Arrest made in Lake Ray Hubbard drowning case, police say

Dallas police arrested 19-year-old Lucas Roper on July 9 and charged him with tampering with physical evidence in the Lake Ray Hubbard case tied to the April 13 drowning death of 18-year-old Daniel Erving near Miller Road in Rowlett. CBS News Texas said Roper was later granted a $10,000 bond.

The arrest moves the case beyond the drowning itself and into what investigators say happened afterward. In the affidavit cited in the case, police allege Roper and a juvenile suspect threw Erving’s clothes into the tree line near a bridge above the lake, and that the juvenile also tossed Erving’s phone from Roper’s vehicle as the group fled. Officers later recovered both the clothes and the phone, and the phone reportedly contained calls and messages between Roper and Erving from the day of the incident.

Investigators also say Roper told police he had communicated with Erving that day to arrange fishing and swimming at the lake, that the three jumped into the water from the bridge, and that Erving drowned. The affidavit says Roper admitted deleting digital communications with Erving because he expected an investigation and did not want to get in trouble. The status of the juvenile suspect remains unknown.

For Rockwall County and the communities that border the lake, the case now raises practical questions about emergency response and witness cooperation at one of the area’s busiest recreation sites. Lake Ray Hubbard has long been a heavily used reservoir with public access points, including Robertson Park, which Texas Parks and Wildlife says offers bank fishing access and two boat ramps. The agency also says there is no camping around the lake.

Local oversight already has a long history. The City of Dallas says Dallas police have provided continuous police protection of Lake Ray Hubbard since 1972 and enforce laws on the lake and up to the shoreline. That role is likely to draw fresh attention as residents assess how quickly officers and witnesses can respond when a lake outing turns into an emergency, and how aggressively authorities will pursue evidence handling in future cases.

The lake itself remains at the center of daily use and weekend traffic. Water Data for Texas reported Lake Ray Hubbard at 98.1% full on July 11, and the Texas Water Development Board says the reservoir was originally called Forney Lake before being renamed for Ray Hubbard, with the dam permit issued March 6, 1959, construction starting June 13, 1964, and impoundment beginning Dec. 1, 1968. The CDC says the U.S. annual age-adjusted drowning death rate was 1.31 per 100,000 people during 2018-2021.
