HOUSTON — A Houston man declared innocent in 2021 after being convicted in a fatal stabbing and serving seven years in prison has been charged with murder in the shooting a fellow motorist, police said.

Lydell Grant, 46, is accused of killing Edwin Arevalo, 33, following a minor traffic collision Thursday night, Houston police said. Police said Grant got out of his vehicle, shot Arevalo and then fled.

Grant was the taken into custody Friday after a warrant was issued for his arrest, police said. He remained jailed Sunday on $1 million bond. The attorney for Grant listed in court records in this case could not immediately be reached on Sunday.

In 2012, Grant was convicted of killing 28-year-old Aaron Scheerhoorn, who was stabbed outside a Houston bar in 2010. Six eyewitnesses to the stabbing had testified against Grant at trial.

But Grant was was declared innocent in May 2021 by the Texas Court of Criminal Appeals after a new analysis of DNA found on the victim’s fingernails pointed to Grant’s innocence. He had served seven years of a life sentence when he was freed on bond in 2019 to await the appeals court’s decision.

In 2019, police arrested Jermarico Carter for Scheerhoorn’s killing. Carter, who was tracked down in Atlanta, confessed to the killing. He pleaded guilty to murder in 2022 and was sent to prison.

The Innocence Project of Texas, which had worked to get Grant exonerated, said in a statement that it couldn’t comment on the specifics of the incident on Thursday, which the group noted is an ongoing investigation. The group said its “thoughts and and sympathies go out to the victim’s family.”
